Doctor Heinz Doofenshmirtz

Built to fail — Artifacts you control have: "if this
would be the target of a spell or an ability destroy
it, this artifact deals 2 damage to any target."
Behold the Inator! — When Heinz Doofenshmirtz enters the battlefield, create a Legendary artifact
token named Inator with Imprint artifact 3. Then
draw 3 cards.
(When this artifact enters the battlefield exile up to 3 artifacts from your hand. This artifact has all abilities
of the exiled artifacts)
