Iron Man, Titan of Infamy

Flying, Haste
Genius Industrialist - Whenever Iron Man attacks, create a Treasure token, then you may sacrifice a noncreature artifact. If you do,
search your library for an artifact card with mana value equal to 1 plus the sacrificed artifact's mana value, put it into the battlefield tapped, then shuffle.
