Simbozz Published June 7, 2026 Updated June 7, 2026

Mega Charizard Y EX & Entei EX is a powerful all-in Fire tournament deck. Mega Charizard Y EX swings for a massive 250 with Crimson Dive — enough to one-shot almost anything in the format — while Entei EX's Legendary Pulse passively draws a card each turn it's Active. Charmeleon's Ignition ability accelerates Fire energy onto your line, and Flame Patch recycles burned energy from the discard for non-stop attacks.

Early Game

Bench Charmander and Entei EX, attach Fire energy and chain draw Supporters to find Rare Candy. On turn one with Mega Charizard Y EX & Entei EX, your priority is finding Mega Charizard Y EX or Entei EX so you can start attaching Fire energy on schedule. If you open with the wrong basic, search aggressively with Professor's Research or Poké Ball before committing energy you might waste. Bench every basic you intend to evolve as early as possible — Mega Charizard Y EX and Entei EX need time to come online, and an empty bench turn one usually loses you the tempo war. Preserve removal Supporters like Cyrus or Sabrina for the mid game; using them on turn one is rarely worth the lost draw. Against fast aggressive openings hinted at by your unfavored matchups (mega charizard y ex is a stage 2 — slow to set up), bench a pivot so a surprise knockout on the active does not strand your evolution line.

Mid Game

Use Ignition / Rare Candy to evolve Mega Charizard Y EX, then swing for 250 with Crimson Dive. By the mid game Mega Charizard Y EX & Entei EX should have Mega Charizard Y EX powered and at least one back-up attacker on the bench. This is the window where the deck's core engine — Mega Charizard Y EX, Entei EX, Charmeleon — has to actively trade prizes. Sequence your attacks so each knockout sets up the next: leave a damaged opposing Pokémon active for Cyrus, or use Sabrina to drag out a benched threat before it can power up. Track your prize trade carefully. Mega Charizard Y EX & Entei EX leans on the strengths "Mega Charizard Y EX one-shots almost every threat in the format with Crimson Dive (250)" and "Entei EX's Legendary Pulse draws a card every turn it's Active", so push the board state that maximises those lines rather than auto-attacking the active. If you fall behind on board, pivot to a single-prize attacker and use this turn to rebuild instead of giving up a multi-prize knockout.

Late Game

Recycle Fire energy with Flame Patch and close out games with repeated Crimson Dive knockouts. Late game with Mega Charizard Y EX & Entei EX is about closing on your terms. Count your remaining prizes and the opponent's, then build the exact attack sequence that wins before they can stabilise. If you are ahead, deny the comeback: knock out their last realistic attacker or use Sabrina to strand a benched Pokémon that cannot retreat. If you are behind, look for an OHKO line using Mega Charizard Y EX — Mega Charizard Y EX & Entei EX typically wins from behind by chaining a single huge turn rather than grinding back evenly. Be ready to spend every remaining Supporter and energy on the closing turn; holding resources "just in case" after the prize race is decided is the most common way to throw a winning position with this deck.

Mulligan Guide & Opening Priorities

The ideal opener for Mega Charizard Y EX & Entei EX is Mega Charizard Y EX + Entei EX in hand with a way to attach Fire energy on the first turn. Mulligan decisions in Pokémon TCG Pocket are limited, so focus on what you keep: prioritise basics that evolve into your key attackers, plus at least one draw Supporter like Professor's Research or Iono. Hold onto Rare Candy or stage-up pieces even if they look dead early — they enable the explosive mid game this deck depends on. Preserve removal cards (Cyrus, Sabrina) for when the opponent has a damaged or vulnerable bench rather than spending them on the first available target.

Common Mistakes

  • Benching Mega Charizard Y EX too early without protection, letting the opponent snipe your main attacker before it is powered.
  • Attaching Fire energy to a Pokémon that will not attack this game instead of building toward your win condition.
  • Spending Cyrus or Sabrina on turn one for tempo when they would have closed a prize two turns later.
  • Evolving on curve into Mega Charizard Y EX without first checking whether you have the energy to attack the same turn.
  • Ignoring the weakness "Mega Charizard Y EX is a Stage 2 — slow to set up" and not boarding a pivot or single-prize back-up in unfavored matchups.
  • Auto-attacking the active Pokémon instead of using Sabrina/Cyrus to set up the knockout sequence the deck actually wants.
  • Burning Professor's Research with a full hand and losing the cards you still needed for the closing turn.
