OP. Eternity can keep this alive forever and Dodotal can be ridiculous. Also, Dodo and Archangel rushes can be very OP. 3/5
Eternity can keep max 3 alive, and to do it you need an Hourglasses otherwise your draw would stuck.
A Dodotal (lovely name) would be slightly stronger than a Frogtal.
Archangel with Dodo would be a strong combo, and I agree, even if Dodo is pretty much weak vs most of CC cards.
But I'll reduce HPs to 2.
