Hello returning player here, I pulled sunday as soon as he came out and quit on the same day, reinstalled the game just now and noticed theres 3 days left on the banner, and I'm wondering if I should grab phainon or tribbie before they leave, I have no idea what happened to the game and the meta and what teams are used now, but knowing gachas 90% are probably obsolete. Only Acheron, Clara,Bronya and Bailu have their 5 star cones. Appreciate any help and advice given. (There are 3 images)
