Reviving!
Iris' power can stay the same but she should be "doomed" (I don't know if it's still gonna be a thing in new patch though) to prevent ridiculous and instant triple-Iris combo in Eredin decks (Iris-Caretaker-Renew Caretaker-Iris again). It can only be countered with Sigrdrifa, Graveyard haters like ghoul and partly Shani. Even when you do they lose significant value. (Banishing a 3 point unit with ghoul is just sad.)
