What are your leaders? It'd be easier to give you some recommendations if we know what your box looks like. If you want, you can put up an account on PadHerder.com and we can give some tips.
Day 1 is likely the way to go for the majority of people. The Chinese series is still one of the best pantheons in the game. Day 2 is good if you really want the Indian 2.0s, but the Chinese are the best overall.

I got some recommendations before but I'm definitely willing to accept more help if anyone has any.
Norns and Kalis are some of the best monsters in the game tbh. Norns are excellent farming leads that can tackle some difficult descends with the right subs and plus eggs. Light Kali is an exceptional sub for many teams, and an excellent leader on her own. Dark Kali is an exceptional sub for many teams.
I've got two rolls for tomorrow and depending on how play today goes I might be able to squeeze out a third. Hopefully I can get one of those.
