Last night when I was doing the Deckathalon, my pet with Maycast Empowerment would only cast the Empowerment spell in reaction to being attacked, as if it were a healing maycast. Previously, aura maycasts would randomly happen if you end your turn without an aura up, regardless of if you cast a blade, trap, heal, attack, etc.
I don't know if this change is intentional, but if it is a bug could it please be fixed?
