Once during your turn (before your attack), you may search your deck for another Deoxys and switch it with Deoxys. (Any cards attached to Deoxys, damage counters, Special Conditions, and effects on it are now on the new Pokémon.) If you do, put Deoxys on top of your deck. Shuffle your deck afterward. You can't use more than 1 Form Change Poké-Power each turn.
Delta Reduction デルタリダクション
During your opponent's next turn, any damage done to Deoxys by attacks is reduced by 30 (before applying Weakness and Resistance).
The Form Change Poké-Power references the ability of Deoxys to change into multiple formes. This card features the Defense Forme of Deoxys.
