So I am planning on getting myself a Miracle Ticket, however I have no idea who I should get. Hopefully will find some good advice from here.

Currently have:

Water:
Strongest team, also have Rudra.
SSR: Asherah, Saraswati, Poseidon
SR: Atalanta, Belphegor.

Fire:
One of my weakest teams with SR's only such as Amon, Agni, Motu, Brynhildr, Ragaraja.

Dark:
SSR: Thanatos
SR: Meretseger, Eligos

Thunder:
Full SR lineup with Baal, Nemesis, Cyclops, Ramiel.

Wind:
SSR: Cu Chulainn
SR: Krampus, Cybele, Principality, Freya

Light:
SSR: Tsukuyomi, Shamash
SR: Djehuti, Diana, Belobog, Uzume, Demeter

Should I continue strengthening my Water lineup or start focusing on others such as Light/Wind?
