Needing some advice on where to go from here. My current SSRs:

Fire: Ares [AW], Svarog [AW], Amaterasu
Water: Poseidon, Ryu-Oh, Saraswati, Nike [AW]
Wind: Odin, Azazel, Gaia [AW]
Thunder: Thor [AW]
Dark: Satan, Susanoo [AW]
Light: Michael, Sol [AW]

Since my Thunder team is in the direst straits, I'm thinking something there, but I main water and secondary fire, so both Cthulhu and Yamaraja are drawing my eye, but then again Titania would just make my Wind team ridiculous. Help?
