Repair Bot

{t}, Remove a scrap counter from a Scrapyard
you control: Regenerate target artifact creature that doesn't have a -1/-1 counter on it. Put a
-1/-1 counter on the regenerated creature.
The most feared steambots aren't the defense-shattering siege engines or the earth-shaking colossi, but the scrappy little repair bots that
keep the others in tip-top shape.
