Elko

+1: Look at the top card of your library. If it's a creature card, you may reveal it and put it into your hand.
-4: Until your next turn, target creature loses all abilities and becomes a green Elk creature with base power and toughness 3/3.
-9: Put three +1/+1 counters and a trample counter on target creature you control. Repeat this process two more times.
