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