For Wind, I'd choose Hastur or Titania. Arguments could be made for either, given that you have Oberon. You'll likely want both eventually. This team will be somewhat weak until SSR Cybele and you'll be relying on Mordred and Sniper Shot.
For Water, Cthulhu is an easy choice. Again, Mordred and Sniper Shot.
For Light, Sol is an easy choice. Since you have Light Tsukuyomi, Mordred is not a requirement and you have the option of running a Burst build. You'll still need Sniper Shot.
