Ok so I am torn on what Kami to get. I main my light team but I have been working on Fire on the side.

My light team is below, grid is around 55,000
Soul: D'art w/ hp weapon
Diana
Michael
Eros
Sol (AW)

Eido is a 3* thunderbird. Considering either Light Tsuki or SSR Art but I don't know which would fit better long term.

My fire team consists of the kami below, grid is weaker at 46,000 but I have Belial to help
Soul: Herc w/ axe
Uriel
Ares
Dakki
Summer Sol

Also have Ama and some other mid level SSRs. Would Svarog or Mars make a bigger impact than one of the two above on my light team? Just torn on where to go from here.
