Cosmos (Grand) Showcase コスモス(リミテッド)

Cosmos is the new grand being released in light and I can see her being a great asset in full auto battles thanks to a party wide def buff (based on how close her life is to 50%), a dispel every ougi and a general high amount of damage output thanks to the massive nukes.
I used a themed team with Yuni, Zooey and Cosmos, but there are more specialized teams that can make her shine even more.

What do you think of Cosmos?
