When your opponent deploys a Ground unit or Character, roll a die. If you roll a 1 or 2, do 2 damage to that unit. If you roll a 3 or more, do 3 damage to that unit.
Enhance: If there are 2 more build counters on Land Mine, if you roll a 1 or 2, do 4 damage to that unit instead, and that damage can't be prevented. If you roll a 3 or more, do 6 damage to that unit instead, and that damage can't be prevented.
