Key Cards
Iron Moth
Primary attacker — Thermal Gust scales damage on coin flips for high Fire pressure.
Dudunsparce
Disruption attacker that discards opposing energy with Sudden Drilling.
Dunsparce
Setup Pokémon that paralyzes early with Sudden Flash.
Magby
Fire energy accelerator via Toasty Toss.
Early Game
Bench Dunsparce and Magby, use Sudden Flash for early paralysis and start accelerating Fire energy with Toasty Toss. On turn one with Iron Moth & Dudunsparce, your priority is finding Iron Moth or Dudunsparce 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 — Iron Moth and Dudunsparce 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 (stage 1 dudunsparce requires the evolution line on curve), bench a pivot so a surprise knockout on the active does not strand your evolution line.
Mid Game
Evolve into Dudunsparce to discard opposing energy and pivot to Iron Moth for Thermal Gust knockouts. By the mid game Iron Moth & Dudunsparce should have Iron Moth powered and at least one back-up attacker on the bench. This is the window where the deck's core engine — Iron Moth, Dudunsparce, Dunsparce — 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. Iron Moth & Dudunsparce leans on the strengths "Dudunsparce disrupts opposing energy with Sudden Drilling" and "Iron Moth applies scaling Fire pressure via Thermal Gust", 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
Chain Thermal Gust swings while Dudunsparce continues stripping energy, using Cyrus and Sabrina for clean finishes. Late game with Iron Moth & Dudunsparce 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 Iron Moth — Iron Moth & Dudunsparce 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 Iron Moth & Dudunsparce is Iron Moth + Dudunsparce 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 Iron Moth 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 Iron Moth without first checking whether you have the energy to attack the same turn.
- Ignoring the weakness "Stage 1 Dudunsparce requires the evolution line on curve" 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.
Card Replacements
Iron Moth fills a unique role in Iron Moth & Dudunsparce (primary attacker — thermal gust scales damage on coin flips for high fire pressure.). 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.
Dudunsparce fills a unique role in Iron Moth & Dudunsparce (disruption attacker that discards opposing energy with sudden drilling.). 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.
Dunsparce fills a unique role in Iron Moth & Dudunsparce (setup pokémon that paralyzes early with sudden flash.). 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.
Iono is a strong universal draw Supporter and slots into nearly any deck if you are missing copies of Professor's Research, though it costs you raw card quantity.
Cyrus pulls a damaged bench Pokémon active; Sabrina lets the opponent choose, but still forces a switch and keeps your closing pressure alive.

Can I play Iron Moth & Dudunsparce without the main Fire engine?
Not really. Iron Moth & Dudunsparce is built around Iron Moth and the Fire energy line — removing that core turns it into a different deck.
