Can You Use Killer Effect on Country Cards in Magic: Collect? 3
I know what the effect is, but I don't know if I can use it on a map of the regions. Does anyone know
You can't use crushers on the ground, you can't use them for anything. If there are annihilators in a creature, then the permanent number of sacrificers is equal to the number of annihilators. You are not aiming for anything with Allied. This means that he can wrap things up or make them irreparable because it will not have a purpose and his opponent will not make sacrifices. It also means that damaged targets cannot be recreated. Anything played after a stage is considered permanent, including pilots, models, creatures, earth, magic, and NS. It does not apply to markings (such as those produced by Elspith Tyrell).

Yes, maps are considered permanent when operated, so they are subject to any effects targeting the permanent.
Edit: Oh, of course, no special alliance. Listen to your son, he is right. A player can choose to sacrifice lands as permanent lands, but you cannot choose permanent lands for them.
