Form Change

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

During your opponent's next turn, prevent all effects of an attack, and any damage done to Deoxys by attacks is reduced by 20 (after applying Weakness and Resistance).
