Albus Dumbledore

Whenever Albus Dumbledore enters the battlefield, draw three cards then put two cards
from your hand on top of your library.
Whenever an opponent casts a spell, you may
reveal the top card of your library. If you do,
counter that spell if it has the same converted mana cost as the revealed card. If you counter a spell this way,
put a +1/+1 counter on another creature you control.
