Unown f

Ability: Guard

Once during your turn (before your attack), if Unown G is on your Bench, you may discard all cards attached to Unown G and attach Unown G to 1 of your Pokémon as a Pokémon Tool card. As long as Unown G is attached to a Pokémon, it is unaffected by the effects of your opponents attacks. If this card as a tool is discarded put it into the Lost-Zone.
