Artifact Creature — Juggernaut 0/0, 4 (4)
Uncommon
Trample
Whenever another artifact enters the battlefield, put a +1/+1 counter on Arcbound Crusher.
Modular 1 (This enters the battlefield with a +1/+1 counter on it. When it dies, you may put its +1/+1 counters on target artifact creature.)
Illus. Michael Sutfin

9/25/2006: If an Arcbound creature gets enough -1/-1 counters to make its toughness 0 or cause the damage on it to now be lethal, the Modular ability will still give another artifact creature a number of +1/+1 counters equal to the number the Arcbound creature had before it got -1/-1 counters.
