Need some advice

Back after a 3 month break. Got the itch to play.

Liquidated my team and have 2.7m coins, 17k training, a legends pack max 93.

Looking to build a new team.

My question is which solos would you guys recommend I focus on to help build the team up again?

zero chill has been pretty good -- coins, snow, players to make sets for zero AP abilities. Ive been currently buying up saints players bout to run a 20 with them.
