Clifftop Beast Slayer

Protection from creatures with power 4 or greater.
Whenever an opponent casts a creature spell with power 4 or greater, foresee 2, then reveal the top card of your library. If it's a creature card with power 3 or less, put that card into your hand. (To foresee 2, look at the card second from the top of your library. You may put that card on the top or bottom of your library, or leave it where it is.)
