Gengar deck guide: lock only when it pays

If you searched for a gengar deck, you usually want more than a spooky name. You want to know when Gengar ex should enter the Active Spot, how to finish Gastly → Haunter → Stage 2 before you lose the race, and which denied Supporter actually changes the next turn. Treat this shell as a Psychic Stage 2 lock plan with a clear failure line: Gengar ex's Active-only Supporter lock matters only when the denied Supporter turn creates a concrete tempo gain.

The repository's dated tournament snapshot covers 30 tournaments, 5,385 decklists, and 14,657 analysed games from July 4 through August 2, 2026 (generated 2026-08-03). That sample publishes no Genetic Apex Gengar ex archetype. Two Mega Gengar ex lists appear only as experimental noise (one list each). This page is a build-and-pilot guide, not a claim that Genetic Apex Gengar sits in today's ranked cut. Check the live Limitless deck explorer before an event.

The short verdict

Build this gengar deck when you already own the Gastly line, want one Active Pokémon that can freeze Supporters for a turn, and are willing to protect a Stage 2 setup. Do not build it on the assumption that locking a random Supporter wins the game. The lock is empty if Gengar ex is not Active, if the opponent can attack or Ability without that Supporter, or if you still have no Energy for Spooky Shot after the denial.

The Gengar ex card page is the local source of truth: a Stage 2 Psychic Pokémon with 170 HP. Shadowy Spellbind prevents the opponent from playing Supporter cards from their hand while Gengar ex is in the Active Spot. Spooky Shot costs three Psychic Energy for 100 damage. Cross-check with Bulbapedia, Game8, and Limitless Pocket A1/123 when a video or translated page disagrees.

What the core cards are asking you to do

Read the list as two clocks. The first asks whether Gastly and Haunter can become Gengar ex before the opponent establishes a knockout. The second asks whether the denied Supporter was the opponent's only way to draw, gust, heal, or finish—otherwise the lock is cosmetic.

Shadowy Spellbind is Active-only

Gengar ex does nothing to Supporters while it sits on the Bench. That single rule drives every pilot decision. Keep a cheaper attacker or sacrifice Active while you assemble the line. Move Gengar ex forward when you can name the Supporter you are denying and say what you gain: an extra Energy attachment, a safer Spooky Shot turn, or a turn where the opponent cannot gust a damaged Bench target.

Historical lock write-ups on Game8, VG247, and Tacter treat the Ability as the selling point. Use them for play-pattern language, then verify Ability text locally. Denying Sabrina, Giovanni, or a late recovery Supporter matters; denying a dead draw while the opponent already has Energy and an attacker usually does not.

The Stage 2 tax is the real cost

Gastly is a 60 HP Basic with Suffocating Gas for 20. Haunter is an 80 HP Stage 1 with Will-O-Wisp for 30. Neither threatens a modern board alone. Rare Candy from Celestial Guardians is the usual speed answer: skip Haunter when the candy is in hand and the Basic is ready. Without candy, count Haunter as a required turn and protect Gastly from early knockouts. Non-ex Gengar (Bother for 50) can fill an awkward mid-game if you need a Stage 2 body without three Energy and an ex prize.

Energy is chosen in the Energy Zone, not the 20-card list. Set it to Psychic for this shell. A mixed Zone that starves Spooky Shot is a common self-inflicted loss. The official Pokémon TCG Pocket site, Pokémon Support battle rules FAQ, and Game8 Energy Zone guide explain why Pocket Energy handling differs from the physical game.

A safer shell for the lock plan

There is no current tournament list to crown as “the” answer. Start with jobs and tune open slots to the cards you own:

Job	Starting choice	Why it belongs
Main lock attacker	2 Gengar ex	Two copies give the lock a second life after the first ex is Knocked Out.
Evolution line	2 Gastly, 1–2 Haunter	Basics find the candy; one Haunter copy covers the no-candy route.
Stage 2 speed	1–2 Rare Candy	Candy turns a three-piece line into a two-piece line when the hand cooperates.
Cheap pressure	0–1 non-ex Gengar or another low-cost Psychic attacker	Keeps the board productive while Gengar ex charges or stays Benched.
Gust and thresholds	1–2 Sabrina, 0–1 Giovanni	Pull a damaged target or cross a precise knockout after Spooky Shot.
Consistency	2 Professor's Research, 2 Poké Ball	Stage 2 decks fail from empty hands more often than from weak Ability text.
Mobility	1–2 X Speed / Leaf	Retreating a stranded Active is often better than forcing an early lock.

For collection routing, open Genetic Apex through the Mewtwo pack for the Gastly line and Gengar ex. Add Rare Candy from the Solgaleo pack or Lunala pack. Pack opening is a collection decision, not a pull-rate promise—cross-check names on Serebii, PokéBeach, and Pokémon GO Hub.

How to pilot the turns

Opening hand: survive before the lock

Keep a Basic Pokémon, a search or draw card, and a believable first attack that does not require Gengar ex on turn two. An opening Gengar ex in hand with no Gastly is not a plan. Ask whether the next two turns still function if Rare Candy never arrives. If the answer is no, bench a partner, attach normally, and treat Spooky Shot as a later ceiling.

When the lock is worth activating

Move Gengar ex Active when three conditions line up: you can attack or threaten Spooky Shot soon, the opponent's next Supporter is consequential, and you are not walking into an immediate knockout that hands over two prizes for nothing. That is the practical meaning of the focus line—Gengar ex's Active-only Supporter lock matters only when the denied Supporter turn creates a concrete tempo gain.

Do not Active-lock while your own hand still needs a Supporter and you have no second attacker. The Ability does not stop attacks, Abilities, Item cards, or Energy attachment. Against decks that win with on-board damage engines, the lock can be almost irrelevant.

After a knockout or a missed candy

When Gengar ex is Knocked Out, the next Active should already have a job: a second Gengar ex charging, a non-ex Gengar finishing a damaged target, or a cheap partner buying one turn. If none of those is ready, the Stage 2 tax just came due. When Rare Candy misses, play Haunter on schedule rather than forcing a dead Active lock with an incomplete line.

Matchup and build choices

In the July 4–August 2 sample, compare this shell to Psychic and disruption neighbours rather than pretending Genetic Apex Gengar is ranked. Indeedee ex / Giratina ex shows 110 lists and a 2.04% share (46.92% win rate over 569 games). Mega Altaria ex / Espeon sits at 115 lists and 2.14% share (54.97% over 735 games). Mega Gardevoir ex / Mega Diancie ex has 97 lists and 1.80% share. Giratina ex / Darkrai ex is a smaller Darkness-Psychic comparison at 20 lists (0.37%). These are orientation points, not substitutes for the Gastly line.

If you want a current ranked Psychic engine instead of a lock project, start with Best Pokémon TCG Pocket Decks 2026 and the broad orientation page Pokémon TCG Pocket Best Deck. For another Genetic Apex Mewtwo-pack Stage 2 story, compare Mewtwo ex deck. The 2025 archive is history: Best Deck 2025.

Against fast Basic ex pressure, protect Gastly and accept that the lock arrives late or not at all. Against Supporter-heavy draw/gust plans, the lock can steal a full development turn—then Spooky Shot has to convert that turn into damage. Against Ability-centric boards, shrink the lock package and keep a cheaper attacker.

Collection route and update rule

Start with the Genetic Apex set page and the Mewtwo pack. If you already own two Gengar ex and the Basics, stop opening for vanity reprints and fill Rare Candy, draw, or switching from the card catalog and Celestial Guardians. Revisit this gengar deck after every expansion: the Ability wording is stable, the meta answer is not. Verify live results in the Limitless explorer instead of treating this dated snapshot as a permanent tier label.
