What happens when you have something like Aethershield Artificer and multiple combat steps (à la helm of the hosts + Aurelia the Warleader)? Does Aethershield Artificer trigger at the start of each combat step?
Yes, Aethershield Artificer will trigger at the beginning of each of your multiple combat phases and its buffs will last for the whole turn, so you can buff multiple artifact creatures across the combats or make an unstoppable juggernaut by piling the buffs on the same creature.
