Steaming Gearhulk

Haste, hexproof
When Steaming Gearhulk enters the battlefield,
look at the top four cards of your library. You may reveal a instant or sorcery card from among them
and put it into your hand. Put the rest on the
bottom of your library in any order. Steaming Gearhulk deals damage to target opponent equal to
the revealed card's converted manacost.
