Fernando, Reveling Raider

Double strike, trample
Fernando, Reveling Raider can't attack alone.
When Fernando, Reveling Raider deals combat
damage to an opponent, you may look at the top
X cards of your library, where X is the amount
of damage dealt. You may reveal a creature card
from among them with mana cost X or less and
put it onto the battlefield. Put the rest on the
bottom of your library in a random order.
