Unown [Z]Reverse Holofoil

Poké-PowerZERO

Once during your turn (before your attack), if Unown Z is on your Bench and you have no cards in your deck, you may discard all cards attached to Unown Z and put Unown Z on top of your deck.

Remove as many damage counters as you like from each Unown you have in play. Put that many damage counters on the Defending Pokémon.
