What's in the box

These are the cards that decide how the deck plays. Each one links to its card page, with its current price.

Koraidon ex

Temporal Forces #120

×2. Kaiser Tackle does 280.

Sandy Shocks ex

Paradox Rift #108

×1. Rotated.

Ancient Booster Energy Capsule

Paradox Rift #159

×4. +60 HP for an Ancient Pokémon.

How it plays

Every Pokémon in this deck is a Basic, so there is nothing to evolve. Koraidon ex's Kaiser Tackle does 280 for three Fighting Energy and 60 damage to itself, and Retribution Strike does 20 plus 10 for each damage counter on Koraidon, so the self-damage turns into a stronger second attack.

Ancient Booster Energy Capsule gives an Ancient Pokémon +60 HP and protects it from Special Conditions, and the deck runs four. Professor Sada's Vitality and Earthen Vessel get the Energy onto the board. Sandy Shocks ex, the other ex, attaches a Fighting Energy from your discard pile to itself each turn once your opponent has 4 or fewer Prize cards left.

Is it Standard legal?

Partly. Koraidon ex (Temporal Forces) carries the H mark, and Ancient Booster Energy Capsule and Explorer's Guidance have H prints. Sandy Shocks ex, Professor Sada's Vitality and Earthen Vessel carry the G mark and rotated on April 10, 2026, which takes most of the deck's Energy acceleration with them.

Every upgrade card below carries an H, I or J regulation mark, the marks legal in Standard since the April 10, 2026 rotation, checked against our Pokémon card catalog on October 10, 2026. Basic Energy is always legal. See which cards are legal in each format for how regulation marks and reprints decide it.

Upgrade path 1: Replace the rotated Energy acceleration

Without Sada's Vitality and Earthen Vessel, Crispin is the replacement: it finds two Basic Energy of different types, puts one in your hand and attaches the other, which suits a Fire and Fighting deck exactly. Lillie's Determination replaces the draw.

Maximum Belt, an ACE SPEC Tool, adds 50 damage against an Active Pokémon ex, taking Kaiser Tackle to 330. It replaces one Ancient Booster Energy Capsule on the Koraidon that is attacking.

Boss's Orders

Ascended Heroes #183

Choose the Pokémon Kaiser Tackle Knocks Out.

What comes out: Sandy Shocks ex and its four non-ex Sandy Shocks, Professor Sada's Vitality and Earthen Vessel.

Upgrade path 2: Add the newer Koraidon ex

Ascended Heroes printed a different Koraidon ex, a Fighting Pokémon. Its Orichalcum Fang does 50, plus 120 more if one of your Pokémon was Knocked Out by an attack on your opponent's last turn, and Impact Blow does 200. It fits beside the deck's Koraidon ex as a comeback attacker, and Fezandipiti ex draws 3 on the same turns Orichalcum Fang is strongest.

Koraidon ex

Ascended Heroes #121

Orichalcum Fang does 170 after you lose a Pokémon.

Fezandipiti ex

Ascended Heroes #142
