Earth Beatrix Skill Damage Team Showcase 土ベアトリクス

Earth Beatrix is one of the best non-limited units that we got in the last few months providing both skill damage (especially using G.Sandalphon weapon in your grid) and auto damage (thanks to the double strike + 50% echo). It takes a few turns to enable her ougi (she needs to be below 50% health to get the buff to enable it), but once she gets going the damage is quite impressive. What do you think of this team?
