Blazing Lance Goddess, Macha

oh nice go in Bi polar Goddess co op with duel Saline then switch places winning shouldn't be an issue

Looking at the leader skill, she'll definitely see use on rainbow-oriented teams. One could begin with a 7x6 leader such as Uruka before switching to Macha for higher multipliers, while pairing with something like Reeche.

The awakenings on this form might not have the same offensive strength as the other ult, but it does have Skill Charge, which will allows you to use the swap active faster.

This one also keeps the balanced type, so you can add any killers to her. Guess that sorta makes up for not having 7c etc that the other one gets.

The only issue is falling below 80% HP. Once that happens, you're left with a measly 1.5x ATK. You'll want to bring lasting shield actives, a recovery stick, or even a 100% shield (Revo Raphael fits this well, letting you stay at full HP for a couple turns while covering two colors Macha doesn't have). Her own shield also helps keep your HP high.
