Khaostra Devoid, Mayhem Witch

When Khaostra Devoid, Mayhem Witch is
played, the controlling player can pay {3} to look
at the top three cards of their opponent's deck. If
any of those cards are an Artifact card, equip that
card to Khaostra Devoid, Mayhem Witch with converted costs to Black and Green. The other
two cards are shuffled back into the opponent's
deck.
