Vigilance, scholarly (You may look at the top and bottom cards of your library. You may do this at any time.)
At the beginning of your upkeep you may pay {2}. If you do, scry 1, then reveal the bottom card of your library. If it's a land card, put that card into your hand. If it's a creature card, put a
+1/+1 counter on target creature. If it's a noncreature, nonland card, you gain 2 life.
