Silent Sword Slash

Target 1 "Silent Swordsman" monster you control; that monster you control gains +3/+3, and if it does, until the end of this turn, it is unaffected by your opponent's card effects. This card's activation and effect cannot be Countered. You can banish this card from your Graveyard; add 1 "Silent Swordsman" monster from your Deck to your hand.
