Best Mega Greninja ex Decks

A Mega Greninja ex deck asks a precise question each time Frogadier is ready to evolve: do you need retreat control, an Active switch, or damage on the Bench? Those jobs belong to different cards. Mega Greninja ex C1-042 has 200 HP, attacks for 100 with two Water Energy and prevents the Defending Pokémon from retreating during the opponent's next turn. Greninja ex B1-073 has an Active-switch Ability. Ordinary Greninja A1-089 places 20 damage with its Ability. Read the versions in the Greninja list before deciding which evolution belongs on the board.

The Mega is a Water and Darkness Pokémon, but the attack still requires two Water Energy. A Mega Greninja deck does not need Darkness generation simply because the card has two types. Check the Energy settings of the complete Greninja list you copy. Spending the next attachment on a different attacker changes when the Mega can attack. A printed Colorless symbol elsewhere in the list is a flexible payment, not a third Energy type you must automatically generate.

Compare a position where an opposing Pokémon has 100 HP remaining with one where it has 120. With no modifiers, the Mega can finish the first in one attack. The second needs another source of damage or another turn. If a Benched A1 Greninja is ready, its 20 damage can change that calculation. That makes an ordinary Greninja valuable inside a Mega Greninja deck; it does not turn the list into a different archetype. Choose a Greninja build by the legal sequence it can produce with the cards actually in play.

Splash of Darkness restricts the Pokémon that received the attack during the opponent's next turn. It does not say that every opposing Pokémon loses every way to switch. A Mega Greninja deck must distinguish the retreat action from a card or Ability that moves Pokémon. Before relying on a second hit, inspect the opponent's possible switch effects and remaining resources. The Greninja build can create a difficult position without guaranteeing that the same target will remain available.

Cyrus can bring a damaged opposing Benched Pokémon into the Active Spot. A1 Greninja can first put damage on that target. If the target is eligible, Cyrus can bring it forward and the Mega can attack it. This is a sequence to evaluate, not an automatic knockout: count remaining HP, your available Supporter action and the two Water attached to the attacker. A Mega Greninja list with Cyrus must find both the damaged target and a useful attack. A Greninja deck cannot choose an undamaged target with Cyrus just because it would be convenient.

Ask what the opponent can do after the first attack. If the target can knock out your Mega immediately, preventing retreat may have achieved little. If the target cannot attack effectively and has no usable switch, the restriction can buy another attack. Practice both boards with the same Greninja list. The value of a Mega Greninja build comes from which Pokémon is trapped and when, rather than treating the words 'can't retreat' as a universal lock.

B1-073 Greninja ex can, once during your turn, switch your Active Water Pokémon with a Benched Pokémon. The Active Pokémon must meet the Water condition; the Ability is not unrestricted movement for every possible attacker. Its own attack also needs two Water and deals 100. A Mega Greninja deck using this version gains a different board action rather than extra damage simply from the ex label. Check which evolution is providing that action in the selected Greninja list.

Suppose Suicune ex is Active and an evolved attacker is ready on the Bench. The Ability can move Suicune without paying its normal retreat cost, preserving attached Energy. The reverse arrangement has another consequence: ending with Suicune Active may give its end-of-turn draw if it remains there. A Greninja build should plan the final Active Pokémon before using the switch. Moving an attacker forward without enough Energy leaves the Mega Greninja deck with a board change and no attack.

A Frogadier can become the Mega, the ordinary version or Greninja ex, but that single evolution line cannot supply all three roles at once. A second line needs another Basic and another legal evolution. When two Greninja lists name the same partner, open both full lists and inspect the core prints and actual card counts. Their stable identities and tournament samples remain separate even when the short labels look similar. The Greninja deck selector reveals the localized full name when a short partner label would collide.

The alternative evolutions also change the survival and point calculation. B1 Greninja ex has 170 HP, a normal retreat cost of two and gives up two points when knocked out. A1 Greninja has 120 HP, retreats for one and can attack for 60 with Water plus Colorless. A Greninja deck choosing the A1 attacker therefore accepts a smaller HP buffer and a different attack. Compare those legal attacks in the Greninja list instead of treating every evolution as the Mega's 200-HP body. This is a version choice within a Mega Greninja build, not permission to move counters or Energy freely between Pokémon.

Suicune ex A4a-020 is a Basic with 140 HP. Crystal Waltz costs two Water and deals 20 damage for each Benched Pokémon on both sides. Its draw Ability triggers at the end of your turn while it is Active. In a Mega Greninja deck, Suicune can therefore attack or help the evolution setup, but a card drawn after the turn ends cannot be used earlier in that same turn. Plan the Greninja build with that timing rather than expecting an immediate search effect.

With two Pokémon on your Bench and two on the opponent's, the unmodified attack deals 80. If both Benches are full, it reaches 120. An opponent who keeps fewer Pokémon Benched changes that damage. A Suicune Greninja deck should count the current board instead of assuming the maximum every turn. Adding another Basic may increase damage, but it also exposes a target and uses a Bench place that an evolution line might need. The Mega Greninja list's best Bench is the one that supports its next decisions.

Suicune's normal retreat costs two Energy. B1 Greninja ex can offer another way to move a Water Active, while the Mega itself has a zero retreat cost. Those are separate resources. If a switch Ability is unavailable, retreating Suicune can delay its next attack. Test the Suicune Greninja build with that Ability ready and without it. Compare the actual attacks each Greninja list can make after the move, and do not treat a free retreat on one Pokémon as free movement for the whole board.

Small Balloon B3b-064 reduces retreat by one only on the Basic Pokémon wearing it. Inflatable Boat A4a-067 reduces retreat by one on the Water Pokémon wearing it. On Suicune's printed two-cost retreat, either applicable reduction alone leaves one, not zero. A Greninja deck cannot carry Small Balloon's Basic-only benefit onto an evolved Greninja. Check the selected Greninja list for actual Tool adoption before adding one, and compare the Energy saved with the Bench space and evolution setup needed for B1's switch Ability. These are alternative movement resources for a Mega Greninja build, not identical effects.

The Mega evolves from Frogadier; it is not a Basic that can be played directly onto the Bench. Put the correct Froakie into play early enough for the evolution plan you intend to use. A Mega Greninja deck with several Stage 2 options still depends on the number of usable starting lines. Read the precise Froakie and Frogadier cards in the complete Greninja list. Different prints can share a name while contributing different HP, attacks or Abilities.

Rare Candy can evolve a Basic into the corresponding Stage 2 from your hand, but it cannot be used on your first turn or on a Basic put into play that turn. It also needs the matching Stage 2 in hand. Saving a middle evolution slot in a Greninja build therefore changes which opening hands work. Compare an opening with an established Froakie against one where Froakie has just entered play. A Mega Greninja list does not remove that timing restriction by including more Candy.

Do not spend the last open Bench place without checking the next evolution. Suicune may help draw, while another Froakie may provide the next attacker or the ordinary Greninja Ability. These roles compete for space rather than automatically improving together. Before changing a Greninja deck, write down which Basic you want to open with, which one must survive and what happens if the first line is knocked out. That gives a concrete reason for choosing one Mega Greninja build over another.

C1 Frogadier has 70 HP and a specific evolution trigger: when played from your hand to evolve one of your Pokémon during your turn, its Ability can put a random Frogadier from your deck onto your Bench. That gives the Greninja deck another potential evolution base without requiring another Froakie first. Leave a Bench place and a Frogadier in the deck. A Frogadier placed directly from the deck does not satisfy the same from-hand evolution trigger, so the Mega Greninja list cannot chain that Ability automatically. If both copies are already in hand, the Greninja build has no Frogadier left in the deck for this effect.

C1 Froakie is a 60-HP Basic whose attack costs one Water and deals 20; its retreat costs one. A1 Froakie instead deals 10 for one Colorless; C1 Frogadier's own attack needs two Water for 30, and it retreats for one. For a Greninja deck these numbers separate an emergency attack from an evolution plan. Paying two attachments for the middle stage's 30 can delay another attacker in the Greninja list. Check the actual opening print before copying a Mega Greninja build: sharing an evolution name does not make the opening attack identical. The older A1-088 Frogadier instead has 80 HP and attacks for 30 with one Colorless, but it does not have C1’s Bench-building Ability. That is a real setup tradeoff in the Greninja list, not an artwork swap.

The Trainer column combines current Greninja builds and reports how many tournament lists included each card. That is adoption by list, not the number of copies you draw and not a sum of unrelated percentages. Open a full Greninja deck to see its allocated copies. A commonly included Trainer may serve setup in one build and recovery in another; the inclusion count alone cannot prove the correct play in your opening hand.

A draw Supporter and Cyrus compete for the same turn's Supporter action. If you need to find an evolution before attacking, spending the action on a target switch may leave the attacker unfinished. If all pieces are ready and a damaged target is available, more cards may be less useful than the immediate target change. Make that choice from the actual Mega Greninja deck position. The Greninja list's frequency table is a starting point for inspection, not an instruction to play the most common Supporter first.

Keep an opening note with three items: the missing evolution, the missing Water attachment and the target the next attack should hit. Then inspect which Trainer in your hand can address that exact bottleneck. Replacing several cards at once makes it hard to tell why a Greninja build improved or stalled. Start from one complete Greninja list, make one explained change and retain the original so that you can compare the two versions with the same opening conditions.

Use Trainer text to identify the missing resource. Professor's Research draws two cards; Poké Ball is an Item that puts one random Basic from your deck into your hand, so it cannot fetch Frogadier or a Stage 2. Copycat first shuffles your hand into your deck and then draws according to the opponent's current hand size. A Greninja deck facing two opposing hand cards gets a different refill from one facing six. Read that count before committing the Greninja list's Supporter action. Copycat is not simply an unconditional extra draw on top of your existing hand.

May puts two random Pokémon from your deck into your hand; for each received this way, you choose a Pokémon from your hand to shuffle back into your deck. It exchanges Pokémon resources rather than guaranteeing two net extra cards. In a Greninja build with both C1 Frogadier copies in hand, returning one can leave a target for the evolution Ability, but the random search and the final hand must still be checked. The Greninja deck may also need Cyrus that turn. Decide between the target change and rebuilding the evolution supply; the Mega Greninja list does not get both Supporter actions.

Mega Greninja ex / Suicune ex

When a Mega Evolution Pokémon ex is knocked out, the opponent receives three points. The Mega's extra HP and free retreat therefore need to be weighed against the point state. A Mega Greninja deck should not expose the Mega merely because it is available to evolve. If the opponent can take all remaining points by knocking it out, check whether the ordinary or ex evolution could accomplish the immediate task with a different point cost. The Greninja build offers choices, not a requirement to choose the Mega every time.

Compare remaining HP with the opposing attack, including its actual conditions, Weakness and any visible modifiers. Mega Greninja's printed Weakness is Lightning. Do not apply a favorable matchup label to every deck that shares a type or assume the dual type removes that weakness. A Greninja deck facing one named opponent archetype has evidence only for the displayed tournament pairings. A Mega Greninja list can have a sound plan and still lose to a particular opening or an unprepared evolution line.

A zero retreat cost can preserve Energy when a legal retreat is available. It does not cancel an opposing effect that prevents retreat, and it does not make a Benched attacker ready by itself. Before moving the Mega out, identify the replacement and the attack it can pay for. Record that decision in practice games with the Greninja build. A Greninja list that saves its Mega but has no useful follow-up may only postpone the same losing point exchange.

The current Greninja deck rows are ordered by tracked list count. Most played does not mean highest win rate. Read games alongside wins and keep the displayed tournament window with any result you share. A smaller Greninja build can move sharply after a few games; a good finish by one entrant does not describe every player. The page only compares win rates when the required game samples exist, and its matchup rows belong to specific opposing archetypes.

The full twenty-card Greninja list on this site is a statistical representative allocated from average card counts across the tracked lists. It need not be the exact submission of any one player. The linked tournament pages are real twenty-card examples of the corresponding builds, with their own authors and event dates. Use a Mega Greninja deck example to understand a real arrangement without assigning the entire archetype's record to that one submission. Card adoption also remains a statement about the tracked sample.

This page covers the Mega form; a deck that only uses ordinary A1 Greninja as another species' partner is outside this selection. Keep the full Greninja list, core version and source together when checking your collection. If a recorded build later becomes archived, its label and last-observed date describe historical evidence and its sample leaves current totals. An accessible old Greninja deck is useful for research, but its continuing URL does not make it a current recommendation.
