Grant (Astral Radiance 144/189)

During this turn, your Fighting Pokémon's attacks do 30 more damage to your opponent's Active Pokémon (before applying Weakness and Resistance). During your turn, if this Grant is in your discard pile, you may discard 2 cards, except any Grant, from your hand. If you do, put this Grant into your hand. (This effect doesn't use up your Supporter card for the turn.)
