Looking for advice on what to spend my miracle ticket on, same as everyone else in this thread. :P

Current SSRs
Fire: Acala, Yamaraja, Uriel, & Dakki
Water: Cthulu, Ryu-oh, Poseidon, & Aphrodite
Wind: Gaia, Titania, Odin, & Azazel
Thunder: Thor
Light: Sol, Light Tsukuyomi, Michael, & Raphael
Dark: Hades

My original intent was to get SSR Cybele as wind is probably my strongest grid, but I tend to play rainbow style for elemental advantage and to make it less boring, so I'm contemplating buffing my thunder or dark teams instead. Any thoughts?
