Dr. Thaddeus "Rusty" Venture

I'm Rusty — When an artifact enters under an opponent's control, create a copy of that artifact, only it's a 0/1 Thopter artifact creature in addition to it's other types with "when this creature becomes tapped, destroy it." This ability triggers only once each turn.

Suffering Bastard —If Dr. Venture would leave the battlefield, put it on the bottom of your library instead.
