There is no single answer to best deck 2026 until you say what “best” is supposed to optimize today. Reviewed October 30, 2026: start with Hoopa ex Mega Absol ex for the highest Tier List score in this snapshot, Dedenne ex Indeedee ex for a strong result over a substantial sample, or Dragonair Mega Rayquaza ex for the new official elite-deck route. These are choices supported by the dated October 29 tournament snapshot, not a solved Dual Fusion ranking.
Dual Fusion is already live. The snapshot used here was generated on October 29, but its last tournament was October 26. New C1 decks are therefore outside this table. Use the established decks below as a starting point while post-release results accumulate; do not treat an older win rate as a forecast for the new format. This article keeps that window fixed; the linked live rankings can contain newer events, including C1.
What the October snapshot actually measures
The window is 2026-09-29 to 2026-10-26, with 25 tournaments, 2,622 decklists and 6,924 analysed matches. Events must be Standard Swiss, have public lists and at least 64 players. The 61 ranked archetypes account for 2,323 lists and 6,137 wins / 12,495 player-game records: 49.1%, the ranked-archetype benchmark. Across all 2,622 lists, the win rate is 48.1% (6,666 / 13,848); ties are included in the denominator and never credited as half a win. Each analysed match contributes two player records. Subset selection explains why these two rates differ.
The 95% Wilson range estimates uncertainty about a stable win probability under an independent-game model; it does not predict the next batch of results. Repeat pilots, different opponents and a new expansion weaken that model. This is tournament evidence, not a ladder win-rate estimate. Small differences between overlapping intervals do not establish that one deck is stronger.
The Tier List score combines 50% performance confidence, 35% meta presence and 15% best finish. It is a site ranking, not a win percentage. The table is sorted by that score; every deck links to its current lists, card usage and matchup samples.
Best deck 2026 shortlist: sixteen measured options
| Score | Deck | Lists | Share | Win rate | 95% range | Games |
|---|---|---|---|---|---|---|
| 97 | Hoopa ex Mega Absol ex | 139 | 5.30% | 52.0% | 48.6–55.5 | 811 |
| 96 | Suicune ex Baxcalibur | 178 | 6.79% | 50.9% | 47.8–54.1 | 960 |
| 96 | Magnezone Miraidon ex | 134 | 5.11% | 51.6% | 48.0–55.1 | 772 |
| 96 | Dedenne ex Indeedee ex | 107 | 4.08% | 53.7% | 49.6–57.7 | 574 |
| 94 | Mega Altaria ex Espeon | 271 | 10.34% | 48.8% | 46.3–51.4 | 1450 |
| 94 | Dragonair Mega Rayquaza ex | 127 | 4.84% | 51.7% | 48.0–55.5 | 688 |
| 91 | Mega Lucario ex Lucario | 162 | 6.18% | 48.4% | 45.1–51.7 | 885 |
| 90 | Hydreigon Mega Absol ex | 78 | 2.97% | 51.4% | 46.7–56.0 | 438 |
| 88 | Mega Altaria ex Greninja | 85 | 3.24% | 49.7% | 45.2–54.2 | 465 |
| 83 | Butterfree Mega Sceptile ex | 130 | 4.96% | 47.6% | 43.9–51.3 | 687 |
| 82 | Vespiquen ex Shuckle ex | 85 | 3.24% | 49.5% | 44.9–54.0 | 459 |
| 81 | Mega Manectric ex Heliolisk | 53 | 2.02% | 49.6% | 43.8–55.5 | 274 |
| 79 | Mega Sceptile ex Greninja | 41 | 1.56% | 51.5% | 45.1–57.9 | 229 |
| 77 | Greninja Mega Absol ex | 19 | 0.72% | 55.7% | 46.5–64.4 | 115 |
| 76 | Mega Blaziken ex | 55 | 2.10% | 48.2% | 42.8–53.8 | 313 |
| 74 | Mega Gardevoir ex Mega Diancie ex | 55 | 2.10% | 47.7% | 41.9–53.5 | 279 |
What changed: Mega Altaria ex Espeon is now the most played archetype at 10.34%, but its result fell from 52.4% in our September 26 snapshot to 48.8%. Hoopa ex Mega Absol ex moved from 2.25% to 5.30% share while its win rate eased from 55.9% to 52.0%. These rolling windows describe different players and opponents; they cannot identify a balance change or a causal reason for the movement.
Dedenne ex Indeedee ex has the highest point win rate among the displayed decks with at least 500 games, 53.7% over 574 games. Its 49.6–57.7% interval is the only one in this table wholly above the 49.1% ranked-subset benchmark. That is a useful screening signal, not a formal test against an independent control group: the benchmark includes these decks, and individual games are not fully independent.
Mega Lucario ex Lucario remains common at 6.18% share and 48.4% wins. Its 45.1–51.7% interval includes 49.1%, so this interval does not establish below-benchmark performance. Familiarity or ownership can justify keeping the deck, but popularity alone does not justify crafting it.
Matchups matter more than a small overall lead
The old Lucario–Altaria–Vespiquen triangle is no longer enough to describe this window. Below, win rate belongs to the first deck. We show sample counts because none of these individual pairings reaches 100 games. They suggest a plan to test, not a guaranteed counter.
The useful tension is clear: Hoopa ex Mega Absol ex beats Mega Altaria ex Espeon in 65% of 86 games, yet manages only 29% against Dedenne ex Indeedee ex over 41 games. Dedenne itself wins just 33% against Magnezone Miraidon ex over 33 games. A promising counter can become the wrong choice when the room changes.
For Dragonair Mega Rayquaza ex, the 70% Lucario result comes from 43 games; its 41% against Suicune ex Baxcalibur comes from 64. Do not turn either cell into a universal ladder recommendation. Open each deck page before committing resources and check whether the matchup sample has grown.
Ten deck cores to inspect before building
The pictures below identify actual core cards, not complete 20-card lists. Click the deck title for tournament lists and the card image for its exact print. Do not combine the highest-usage cards into an invented list: flex slots, evolution counts and Energy choices must come from one coherent list.
Hoopa ex Mega Absol ex
The Darkness package pairs Hoopa ex, Mega Absol ex and Darkrai ex. All three appear in at least 90% of sampled lists. Pick it when you already own the package and expect Altaria / Espeon. Its leading score and 811 games justify a shortlist place, but the Dedenne and Vespiquen matchups are reasons to test first.
Dedenne ex Indeedee ex
Dedenne ex, Indeedee ex and Oricorio appear in at least 90% of these 107 lists. This is the new priority to inspect, rather than a promise of easy wins. The 53.7% overall rate hides poor results into Lucario and Magnezone. Copy a proven list and check its Energy plan before treating the Pokémon pair as a self-contained engine.
Magnezone Miraidon ex
This variant uses Magnezone, Miraidon ex and Magneton. Its 134 lists and 772 games make it a meaningful comparison with Hoopa. The 67% Dedenne result is based on only 33 games, while the Lucario pairing is 34% over 56. See the electric deck guide for other Lightning engines; the separately classified Miraidon / Magnezone variant must not inherit this row's record.
Dragonair Mega Rayquaza ex
Mega Rayquaza ex, Dragonair and Gouging Fire form the official newly gifted elite deck's headline package. This makes checking your Gifts more useful than assuming you must open several older sets. The 51.7% result belongs to tournament-built versions, not necessarily the gift list. Compare the received list with the linked archetype before changing it.
Suicune ex Baxcalibur
Suicune ex, Baxcalibur and Chien-Pao ex remain the larger Water sample: 178 lists and 960 games. Its 50.9% overall result and favourable Rayquaza pairing make it worth retaining if complete. Stage 2 setup is still a cost, and the data does not establish it as better than every competing engine.
Mega Altaria ex Espeon
Mega Altaria ex, Espeon and Darkrai remain the format's most visible package. The 1,450-game sample is useful, but 48.8% is no longer the September recommendation. It wins 62% against Lucario over 97 games and just 33% against Hoopa over 86. Keep those opponents in mind before calling it an all-rounder.
Hydreigon Mega Absol ex
Hydreigon and Mega Absol ex offer another Darkness path, with Bombirdier in at least 90% of lists. Its 51.4% over 438 games is an option for an existing collection, not evidence that it replaces Hoopa. Check the evolution slots and actual list first; sharing one attacker does not make the two archetypes interchangeable.
Mega Altaria ex Greninja
The older Greninja package is a distinct Altaria archetype at 49.7% over 465 games. Rare Candy appears in its current core. This Greninja is an A1 card, not the new C1 Mega Greninja ex. Use this alternative when you already own the evolution package and want to compare real lists, without borrowing Espeon's sample or C1 hype.
Butterfree Mega Sceptile ex
Butterfree with Mega Sceptile ex still has 130 lists, but the overall result is now 47.6%. It records 51% against Altaria over 71 games, which does not support a claim that it is the best Altaria counter. Two evolution packages and Quick-Grow Extract deserve a consistency check before you spend on the deck.
Vespiquen ex Shuckle ex
Vespiquen ex, Shuckle ex and Teal Mask Ogerpon ex offer another Grass route. The overall 49.5% hides a 77% Hoopa result over only 26 games. That is a lead to investigate, not enough to replace the whole shortlist. Its widely spread support cards also make collection fit more important than the two headline Pokémon.
Four more illustrated options for an existing collection
These decks broaden the comparison without changing the sixteen-deck ranking above. Their smaller samples cannot support the same confidence as the leading choices. Start here if the pictured cards are already in your collection, then open one complete tournament list before deciding which version to try.
Zoroark ex Mega Absol ex
Zoroark ex and Mega Absol ex share a Darkness attacker with the leading Hoopa shell, but this version adds the Zorua evolution package. Its 26 lists produced 58 wins in 136 games, or 42.6%. That result does not justify switching simply because the Pokémon look compatible. Compare the development slots and opening hands with Hoopa ex Mega Absol ex; owning Absol is a useful starting point, not proof that every Absol variant is equally strong.
Mega Sharpedo ex Gyarados
Mega Sharpedo ex with Gyarados produced 56 wins in 119 games: 47.1%, from 22 lists. The Carvanha line gives you a different build to examine if you already collected Water cards, but the shared type does not make it a cheaper substitute for Suicune. Check both evolution packages in the linked list. Count missing Basics and duplicates before valuing the headline Pokémon; one missing setup piece can leave a nearly complete collection unable to build the list.
Mega Diancie ex Carbink
Mega Diancie ex, Carbink and Flutter Mane appear in at least 90% of this archetype's lists. It posted 56 wins in 110 games, or 50.9%, across 20 lists. That is enough to inspect, not enough to declare a dependable advantage. Open the exact Carbink version: the separately classified Flutter Mane ex pairing has another sample. The ordinary Flutter Mane pictured here and a Pokémon ex print are not interchangeable evidence or automatic substitutions.
Hydreigon Mega Sableye ex
Already have Hydreigon? This version pairs it with Mega Sableye ex rather than Mega Absol ex, retaining the Deino evolution route. Its 16 lists recorded 50 wins in 97 games, or 51.5%. Compare it directly with Hydreigon Mega Absol ex to see which complete list your collection can finish. A result on fewer than 100 games should guide an experiment, not persuade you to abandon a familiar attacker or spend heavily on a new one.
Collection cost: start with missing cards, not set count
A count of source sets is not a price. Reprints, cards already owned and the new gift deck all change the real cost. Check the Tracker, then compare one complete list in the Deck Builder. Count missing attackers, evolution pieces and essential Trainers separately; do not substitute an engine card just because another Pokémon has the same type.
For the shortest acquisition route, check the Rayquaza elite deck before opening Ruler of the Skies. For Dedenne, inspect Everyday Wonders and Mega Rising; for Miraidon, inspect Paradox Drive and the older Magnezone pieces. Deluxe Pack: Mega is a reprint option, but a guaranteed rarity is not a guarantee of the missing card. The Deluxe Pack Mega guide explains that distinction. These are collection routes, not a claim about expected pack cost.
More deck links for the cards you already own
Already own the nearby engines? Compare Mega Manectric ex Heliolisk with Magnezone rather than replacing all your Lightning cards. For Greninja owners, also inspect Mega Blaziken ex Greninja and Mega Sceptile ex Greninja. If you already built a Darkness shell, Greninja Mega Absol ex offers another actual archetype to compare. Mega Charizard Y ex Entei ex remains an option for an existing Fire collection, but its 46.2% over 299 games is a reason to review it carefully.
These are alternative lists, not extra top recommendations. Use their sample counts and full lists to decide whether a small modification beats starting a new collection.
Compare versions before buying into a deck name
A shared headline Pokémon can conceal a different deck. Compare Mega Altaria ex Espeon with Mega Altaria ex Greninja: the support lines and tournament records belong to separate archetypes. Likewise, Hoopa ex Greninja has 109 games at 49.5%; it cannot borrow Hoopa / Absol's 811-game record just because both contain Hoopa. The separately classified Miraidon ex Magnezone sits at 45.5% over 99 games, whereas Magnezone Miraidon ex has the larger sample in the main table.
Treat these as classification boundaries, not proof that changing a single partner causes the difference. Before comparing rates, open the actual lists, check which cards define each variant and confirm that the tournament windows match.
A practical trial before spending more resources
Choose a complete list from Hoopa ex Mega Absol ex, Dedenne ex Indeedee ex or Dragonair Mega Rayquaza ex, then record ten games without changing cards. For every loss, note whether the problem was an unavailable evolution, an Energy requirement, a missed sequence or an opponent you repeatedly faced. Also note first or second turn; do not invent a matchup conclusion from two encounters.
Change one functional role only after you can state the problem it should solve. If you replace a consistency card with another attacker, count the setup cards you removed and test the same opening plan again. Keep the original list so you can reverse the experiment. Ten games are a usability check for your own piloting and collection, not a reliable win-rate estimate or proof that a published archetype is wrong.
Dual Fusion: what is confirmed and what still needs results
The official release announcement confirms Dual Fusion is available. Its announced launch time was October 28 at 6 p.m. PDT, which is October 29 at 09:00 in Shanghai. Mega Mewtwo X ex and Mega Greninja ex introduce new dual-type packages. Their pictures below are release context, not a ranked recommendation.
The official announcement also confirms six current rental decks and the Rayquaza elite gift. The October producer letter describes repeat-use rentals and Community Decks as ways to try and copy decks. Try the new packages before spending resources, then revisit Latest Additions for archetypes supported by the site's newer datasets. A newly released card is not automatically the best deck.
An external current tier list already separates new C1 entries from established decks, but its filters and 90% intervals differ from our 95% intervals. Do not average the two sites' rates or insert those results into this table. Check the live rankings for post-C1 tournaments and compare their window before using newer figures.
Questions before choosing a deck
Which is the best deck 2026 right now?
Hoopa / Mega Absol leads this article's dated pre-C1 Tier List score; Dedenne / Indeedee has the strongest point result among the displayed decks with at least 500 games. Neither is a proven Dual Fusion winner. Check the date on Meta rankings before copying a recommendation.
What is the cheapest starting point?
First check the Rayquaza elite deck in Gifts. Otherwise, finish the deck whose essential pieces you own. The old “three sets means cheap” shortcut misses reprints, free cards and missing duplicates.
Should I craft Mega Greninja ex immediately?
Not on the evidence in this article. The tournament window ends before C1. Use rentals and inspect Dual Fusion first, then wait for relevant results if the craft is only for competitive strength.
Choose your best deck 2026 shortlist
Shortlist Hoopa, Dedenne and one deck your collection already supports. Check the bad matchups, copy a complete list and play a small fixed-list trial before changing roles. A ten-game trial can reveal sequencing problems, but cannot establish a true win rate. Keep resources available for more evidence from the Dual Fusion format.
Use Tier List for the current ordering, Latest Additions for new entries, and best-deck decision guide for the broader deck-selection method. Best Deck 2025 archive preserves the older year as history; compare dates before comparing results.
