PokÃ©-Power Form Change
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 Conditions, and effects on it are now on the new PokÃ©mon.) If you do, put Deoxys ex on top of your deck. Shuffle your deck afterward. You can't use more than 1 Form Change PokÃ©-Power each turn.
When PokÃ©mon-ex has been Knocked Out, your opponent takes 2 Prize cards.
