Amaroq, the First Wanderer

Whenever you cast a wolf spell with converted mana cost 3 or greater, reveal cards from the top
of your library until you reveal a wolf card that costs less. Cast that card without paying its mana cost and put the rest on the bottom of your library in random order.
If Amaroq, the First Wanderer would be put into the graveyard or exile from anywhere, you may shuffle him into your library instead.
