Trap counter

Trap counters are a type of counter introduced in Scourge. They are placed on lands that give them a sacrificial ability to deal damage to creatures. 
==Description==
Trap counters first appeared on <c>Trap Digger</c> in Scourge. It is a creature with an activated ability to place Trap counters on lands under the Player's control. These lands can then be sacrificed to deal 3 damage to a creature without flying. This represents the land being trapped and activating on the creature with flying creatures being immune as they can stay above the land.
