Unown UF C

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

Search your opponent's discard pile for a Supporter card and use the effect of that card as the effect of this attack. (The Supporter card remains in your opponent's discard pile.)
