Iron Man, Titan of Innovation

Flying, haste

Genius Industrialist — When Iron Man attacks,
create a Tresure 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 onto the battlefield tapped, then shuffle.

"I have a plan... attack!"— Tony Stark
