Ultron, Unlimited

Legendary Artifact Creature — Robot Villain

Flying Whenever Ultron attacks, he connives. (Draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on this creature.) Whenever a creature you control connives, you may pay {1}. If you do, create a 2/2 colorless Robot Villain artifact creature token.
