I'm looking for roster advice. my roster is pretty bad. I quit the game after the 2nd Kafka banner (I'm F2P). I recently just started rolling on the Saber banner because I wanted another Wind character (I literally only had Dan Heng).

I only have 20k Jades Left. My question is, which banner should I spend this on? Saber, Archer, Phainon or Sunday? and who to spend mats on?
