So I have a question from the Core set:
So Empire's Church of Sigmar says that "opponents can't target your units with card effects unless they pay additional 1 resource per effect."
So if I play orks and have Troll Vomit that states: Play during your turn: Action: "Destroy all units in play", since it's a "card effect" that targets all units, does this mean I have to pay 1 resource to destroy each of the Empire's units in play? Say Empire has 5 units, will this cost 5 extra resources? If I only have say 3 resources left after I cast Troll vomit, can I kill 3 out of those 5 units in that case? And who would choose which units to kill- me, or the opponent?
