PokÃ©-Power Form Change
Once during your turn (before your attack), you may search your deck for any Deoxys and switch it with Deoxys Attack Forme. (Any cards attached to Deoxys Attack Forme, damage counters, Special Conditions, and effects on it are now on the new PokÃ©mon.) If you do, put Deoxys Attack Forme on top of your deck. Shuffle your deck afterward. You can't use more than 1 Form Change PokÃ©-Power each turn.
Psychic Boost 80
During your next turn, Deoxys's Psychic Boost attack's base damage is 20.
