Updated June 9, 2026Iron Valiant and Mega Altaria ex Deck Guide in Pokémon TCG Pocket
A Future-focused deck that pressures early and finishes strong with Mega Altaria ex's scaling damage.
This deck combines the early-game aggression of Future Pokémon with the late-game power of Mega Altaria ex. Iron Valiant's Future System Ability reduces attack costs for Future Pokémon by Colorless, enabling fast and efficient plays, while Mega Altaria ex's Mega Harmony attack scales with your Benched Pokémon to close out games. The strategy excels at applying consistent pressure while maintaining energy efficiency.
The decklist
How it works
Iron Valiant is the engine of this deck with its Future System Ability, which
reduces attack costs for your Future Pokémon by Colorless.
This enables Iron Crown to attack for Colorless with
Enumerating Blade (reduced from [C+C]) and makes Iron Boulder's Modular Axe
more manageable at [P+P+C] instead of [P+P+C+C]. Its 100 HP makes it
vulnerable to Metal-type attackers, so protecting it on the Bench is crucial.
Mega Altaria ex serves as your finisher with Mega Harmony, dealing 40 base
damage plus 30 more for each of your Benched Pokémon. With a full Bench of 3
Pokémon, this reaches 130 damage, enough to Knock Out many popular attackers.
Its 190 HP makes it durable, and the 1 Retreat Cost means it's easy to pivot
out if needed. The attack cost of Psychic
Psychic remains unchanged because Mega Altaria ex is not a
Future Pokémon, so Future System does not apply to it.
Iron Crown applies early pressure with Enumerating Blade, dealing 10 damage
plus 20 more for each of your opponent's Benched Pokémon. Against a full Bench
of 3 Pokémon, this hits for 70 damage, enough to threaten many Basic Pokémon.
The attack normally costs [C+C] but becomes Colorless with
Iron Valiant's Ability. Its 100 HP means it's best used early before opponents
can power up stronger attacks.
Iron Boulder is your mid-game attacker with Modular Axe, dealing 80 damage. With Iron Valiant's Ability, the attack cost drops from [P+P+C+C] to [P+P+C]. Its 120 HP gives it decent staying power, and the damage output can pressure opponents into trading their lower-HP Pokémon for it. The Darkness weakness is less common than Metal, making it more durable than Iron Valiant.
Matchups
| Matchup | Favorability | How to play it |
|---|---|---|
| Water decks | Favored | Use Iron Crown to pressure their Bench early. With a full Bench of 3 Pokémon, Mega Harmony hits 130 damage, enough to Knock Out Chien-Pao ex, though bulkier threats like Baxcalibur survive. Keep Iron Valiant protected from potential Metal tech cards. |
| Slow Stage 2 decks | Favored | Apply early pressure with Iron Crown and Iron Boulder to disrupt their setup. Target their Basics before they can evolve. Mega Altaria ex can clean up their evolved Pokémon. |
| Balanced meta decks | Even | Keep Iron Valiant in play so Future System keeps your Future Pokémon attacking cheaply. Time your Mega Altaria ex plays carefully to maximize damage. Use Copycat to maintain card advantage in longer games. |
| Fast aggressive decks | Unfavored | Prioritize setting up Iron Boulder to trade efficiently. Use Peculiar Plaza to retreat damaged Pokémon. Don't overextend your Bench against decks that can punish it. |
| Metal-type decks | Unfavored | Protect Iron Valiant at all costs, as it's weak to Metal. Mega Altaria ex shares that Metal weakness, so lean on Iron Crown and Iron Boulder, which are weak to Darkness instead. Consider benching Swablu early to absorb hits. |
Tech options and swaps
The tech cards in this deck are carefully balanced. Future Booster Energy Capsule boosts Future Pokémon damage. Peculiar Plaza helps manage Retreat Costs for your Psychic Pokémon. Copycat provides crucial hand refresh in longer games. If facing many Metal decks, consider cutting one Poké Ball for a Potion to keep your Metal-weak attackers out of knockout range.
How to pilot it
Prioritize getting Iron Valiant into play early - it's your most important starter. Ideal opening sequence:
- Turn 1: Bench Iron Valiant and attach energy to it. Use Professor's Research to draw toward key pieces.
- Turn 2: Play Iron Crown or Iron Boulder with Future Booster Energy Capsule. Start attacking with reduced energy costs.
- Turn 3-4: Build your Bench while maintaining pressure. Prepare Swablu for evolution.
- Turn 5+: Evolve into Mega Altaria ex when you can maximize its damage output with a full Bench.
Energy sequencing is crucial - prioritize attaching to Iron Valiant first, then your attackers. Common misplays include overextending your Bench too early or playing Mega Altaria ex before you can fully power its attack.
