Kashar, the Old One

{x}{r}{g}: Target werewolf gains trample and
+X/+X until end of turn.
Whenever Kashar, deals combat damage to
an opponent, or planeswalker you may look at
that many cards off the top of your library
reveal a human card and put it in your hand,
then put the rest on the bottom of your library
in a random order. If you do, transform Kashar.
I will not rest...
