Deoxys-ex

Once during your turn (before your attack), you may search your deck for another Deoxys ex and switch it with Deoxys ex. (Any cards attached to Deoxys ex, damage counters, Special Condition, and effects on it are now on the new Pokémon.) If you do, put Deoxys ex on top of your deck. Shuffle your deck afterward. You can't use more than 1 Form Change Poke-Power each turn.

You may discard 2 Energy cards from Deoxys ex. If you do, this attack does 50 damage plus 30 more damage for each Energy attached at the Defending Pokémon.
