Based on previous information

Lancer is Cu

Saber is obviously Artoria

Archer is Emiya

Since Sparxie, Castorice and SW will also appear I guess:

Castorice will probably be Rider because of Pollux

Sparxie should be Caster

SW should be assassin

Which leave Berserker for Phainon. I mean it was either Berserker or Saber but that slot is taken already by Artoria

Unless I'm mistaken, >!Asat !<may be refering to Phainon when he say a "new hire who switched sides immediately"
