The card says:
"Quest. Action: Sacrifice the unit on this quest to destroy up to two target attacking units. Use this ability only if A Glorious Death has 3 or more ressource tokens on it."
If I attack, can I trigger the quest (it has 3 or more ressources on it) and kill nobody (just the sacrificed unit)? The card says "up to two"... In the case that my deck runs out of cards, this is an effective way to kill unwanted units. Additional it can trigger the ranger's abiltiy and I can resurrect the sacrificed unit to place it fin another zone.
