Artifact Creature — Robot — {5}{R}{R}

When this creature enters, any number of target noncreature artifacts you control become 3/3 artifact creatures. Sacrifice them at the beginning of the next end step. Each artifact creature you control has melee, trample, and haste. (Whenever a creature with melee attacks, it gets +1/+1 until end of turn for each opponent you attacked this combat.)
