So I remember the thread on Perpetual Priesthood and Priests of Christ, and thought I'd ask. I've always thought when you bring a character into battle, by banding or a card like Perpetual Priesthood, if applicable their ability activates. Like if you played Sound the Alarm and banded in Abishai, he would still be able to band in a red brigade Warrior Class Hero. Or if The Strong Angel gets banded into battle, his ability kicks in and makes the battle by the numbers and kicks himself out of it. Is there a difference between banding someone into battle, and exchanging them?
