I was playing a duel against a guy. I was using Haven with Axel, and he was using Academy, I don't remember the name of the sorceress. Anyway, I was winning, and then he cast Armageddon twice in a row, and it killed my angels. Then he finished off my knights, resurrected his Rakshasa, and almost defeated me. But then something strange happened. An angel appeared on the battlefield with no health, and it resurrected my knights, even though the angels had already used that ability in the game. Does anyone know what ability this is?
