Sky-Splitting Deoxys(裂空のデオキシス)

Forme Change

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