Shona has an attack with the green die. But you are correct in that the underdog decides who applies the critical block first
You are forgetting Shona Carano and her Hit the Blade attack! It's the one she uses when she's looking for displacement effects. EDIT: Sorry, seems I missed new posts were moved to the next page. Is it posible to increase the number of posts per page?
Eclypse is the best one combined with the two brothers. Moon Cycle permit her to flip more than one state on a target. Polarization is the perfect card to combine with Bach and Hammerhead too. You can play a team that kill enemies without them having chances to roll their DEF. That good for two things , First they can do nothing against damage and then you negate the chance to activate some switch.
Extremely keen to slot Hammerhead into my roster and see how he performs. He definitely needs someone to manage that health with him though, Mendoza is a good pick but Parvati is probably more flexible.
