Nyssa of the Wildered Rock

Flying, double strike
Whenever Nyssa deals combat damage to a player create a treasure token.
{2}: Exile Nyssa. If you do, put a land you control
onto the bottom of your library, then reveal cards
from the top of your library until you reveal a
land card, and put that card onto the battlefield.
Shuffle the rest of the revealed cards into your
library. Return Nyssa to the battlefield under
your control at the beginning of the next end step.
