(Whenever you would draw a card outside of your draw step, you may draw an additional card. If you do, put two cards from your hand on the bottom of your library.)
Whenever a card is placed on the bottom of your library from anywhere, target creature you control can't be blocked until end of turn and has "When this creature deals combat damage to a player, untap target permanent you control."
