Mud, Alert Ranger

Reach.
Whenever a creature an opponent controls
attacks you, its controller may pay {1}. If they
don't, Mud deals 1 damage to that creature.
{x}{t}: If you control an artifact with a mimic
counter on it, sacrifice it. Then, create a token
copy of target artifact an opponent controls with
mana value less than X and put a mimic counter
on it. Activate only as a sorcery.
