So I decided to, ah, try to figure out how many Masters are left for the convenience of anyone thinking to make new CSs or anything

Esra: True Assassin
Nigel/Ameiseviel/Mel: Archer
Rin: Saber
BB/Lax: Caster
Kuroneko's: ???
Caster: Fake Assassin (though I'd like to think anyone can summon him, as long as you do it faster than Caster)

That leaves 2 Masters open (unless people start forming teams), [s]and I [i]think[/i] Class Rep [i]someone[/i] is making Shirou, so 1 more spot.[/s] Tatsua, are you making a Master?

EDIT: Oh, and the available Servants to partner with are Rider, Lancer, and Berserker.
