I’m in the dual class Arena today with Shaman class + Paladin hero power. I drafted Hagatha the Fabled, along with Crater’s Aura.
In one of my matches, I played Hagatha which drew Crater’s Aura, thus a Fairy Tale Slime was added into my hand which is supposed to cast Crater’s Aura on its battlecry. However, after I played the slime, nothing happened! I think I saw the aura appeared for a split second but it disappeared right away. I also confirm the end of turn effect of the aura didn’t happen.
