Mega Charizard Y EX & Iron Moth is an aggressive Fire build that combines Mega Charizard Y EX's 250-damage Crimson Dive closer with Iron Moth's scaling Thermal Gust pressure. Charmeleon's Ignition ability accelerates Fire energy from the Energy Zone, while Iron Valiant's Future System reduces attack costs on Future Pokémon, letting the deck swing efficiently for huge damage from turn three onward.
Open Charmander and start building the Mega Charizard line, leaning on Iron Moth for early Thermal Gust pressure. Use Charmeleon's Ignition to accelerate Fire energy onto Mega Charizard Y EX, then chain Crimson Dive knockouts while Iron Valiant discounts your Future attackers. Flame Patch keeps the engine alive in longer games.
Primary closer — Crimson Dive hits 250 for clean one-shot knockouts.

Recycles Fire energy from the discard pile for tempo turns.
Bench Charmander and Iron Moth, attach Fire energy, and start applying Thermal Gust pressure while building toward Mega Charizard Y EX. On turn one with Mega Charizard Y EX & Iron Moth, your priority is finding Mega Charizard Y EX or Charmeleon 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 Charmeleon 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 — needs the line on curve), bench a pivot so a surprise knockout on the active does not strand your evolution line.
Evolve into Charmeleon to trigger Ignition, accelerate Fire energy onto your bench, and promote Mega Charizard Y EX with Iron Valiant supporting from the bench. By the mid game Mega Charizard Y EX & Iron Moth 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, Charmeleon, Iron Moth — 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 & Iron Moth leans on the strengths "Mega Charizard Y EX one-shots most threats with Crimson Dive" and "Charmeleon's Ignition accelerates Fire energy onto attackers", 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.
Close with chained Crimson Dive knockouts, using Flame Patch and Professor's Research to refill the engine. Late game with Mega Charizard Y EX & Iron Moth 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 & Iron Moth 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.
The ideal opener for Mega Charizard Y EX & Iron Moth is Mega Charizard Y EX + Charmeleon 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.
Mega Charizard Y EX fills a unique role in Mega Charizard Y EX & Iron Moth (primary closer — crimson dive hits 250 for clean one-shot knockouts.). If you do not own it, the deck cannot be rebuilt around a single swap — consider playing a different Fire archetype until you can craft it.
Charmeleon fills a unique role in Mega Charizard Y EX & Iron Moth (engine — ignition accelerates fire energy from the energy zone onto charizard.). If you do not own it, the deck cannot be rebuilt around a single swap — consider playing a different Fire archetype until you can craft it.

Cyrus pulls a damaged bench Pokémon active; Sabrina lets the opponent choose, but still forces a switch and keeps your closing pressure alive.
