Strategy Guide
Auto-generatedMega Charizard Y ex aims to land Crimson Dive — 250 damage from four energy — to one-shot nearly any Pokemon in the format. Because a single KO of the Mega costs your opponent 3 points and ends the game immediately, the plan lives and dies on getting Crimson Dive off before the opponent can reach 3 points first.
Use Poké Ball to find Charmander, then rely on Professor's Research, Copycat, and draw supporters to reach Charmeleon and Mega Charizard Y ex through natural draw. Flame Patch builds energy on the bench while you develop the evolution line. Entei ex provides an early attacker that can threaten points while Charizard charges. Once Crimson Dive is ready, a single hit can KO any Pokemon in the format except the sturdiest Megas, scoring 1-3 points in one attack. Pokémon Center Lady and Lucky Ice Pop manage the 50 self-damage Crimson Dive inflicts.
Damage Math
Any Pokemon with 250 HP or less
Crimson Dive base 250 = one-shot KO
Most Pokemon in the format have 250 HP or less; Crimson Dive ends them in one hit

50 self-damage per Crimson Dive use
Pokémon Center Lady and Lucky Ice Pop offset this to extend Charizard's lifespan
How to Play
Accelerate Energy Onto the Bench
Flame Patch places Fire energy on benched Fire Pokemon, letting you pre-charge Mega Charizard Y ex before it enters the active spot. Pair this with Entei ex as your turn-one or turn-two attacker so you are scoring points while Charizard charges. Four energy for Crimson Dive becomes reachable within a few turns of Flame Patch setup.
Heal Through Self-Damage to Sustain Crimson Dive
Each Crimson Dive deals 50 damage back to Mega Charizard Y ex. Pokémon Center Lady removes damage, and Lucky Ice Pop prevents some. Without healing, two Crimson Dives self-KO the attacker. Managing that self-damage is essential to getting a second or third attack off before opponents can react.
How to Beat This Deck
Race to 3 Points Before Crimson Dive Fires
Mega Charizard Y ex needs multiple turns to charge. Decks that score two quick KOs on ex Pokemon — netting 4 points total — can win the game before Charizard ever attacks. Aggressive ex-targeting strategies that chain two 2-point KOs shut down the whole plan.
Exploit Water Weakness or High-HP Tanks
Mega Swampert ex and Guzzlord ex sit at 25% for this archetype, indicating water-type attackers and high-bulk decks can absorb one Crimson Dive and KO back. Pokemon with more than 250 HP that hit for weakness force Charizard to attack twice, leaving it vulnerable to self-damage.
Disrupt the Evolution Chain
Cyrus or hand-disruption trainers can stall the Charmander-to-Charmeleon-to-Mega path. Because Poké Ball only finds Charmander, the higher evolutions depend on draw — a bad hand forces a missed attack turn. Disrupting during those setup turns prevents Crimson Dive from ever landing.
