Onatel or Queen of Hearts at tank?

Meh, the AI not knowing how to use her special is a bit overstated I feel, sure, if she hits 2, that’s not ideal (same for any splash attacker), but if your concern is about her ability to overwrite herself… if she’s gaining enough mana to be doing that, she’s doing pretty dang well. Her firing twice generally means the attacker is very far behind, so she’s done her job already.
