I'm curious what people would recommend for me to focus on. I have a number of SSR's scattered over all the types so I haven't really focused on any one type yet. I'm able to blow through Ultimate advents of each type with little issue although most ragnaroks still require an elixir to clear.

I've currently got the following with a good selection of SR's to round out each team.

Dark - Satan, Amon Unleashed
Light - Michael, Sol
Fire - Amaterasu, Acala
Wind - Titania, Odin, Gaia
Water - Shiva, Ryo-Oh
Thunder - Tyr, Raido, Brahma

I'm leaning towards Cthulhu or maybe Savarog for a miracle ticket at this point but any advice would be most welcome.
