I was playing a game with 2 Rot Wolves and a Mondronen Shaman (which was transformed into a 5/5) on the battlefield. I attacked with all of them, and my opponent blocked my Shaman with Banisher Priest. He exiled my Immerwolf with it, and the Priest died, so my Immerwolf came back from exile. Immerwolf gives all wolves and werewolves I control +1/+1, so does that +1/+1 apply to my Rot Wolves before they deal their damage to my opponent? Or does the +1/+1 affect my creatures next turn on?
