I'm am cursed with Gold Casters. I've been trying so hard to get Kama or Pavarti but have had no luck. Finally see the shine of a gold Servant and I get excited. Get Nicotis and face palm and she goes immediately to the bottom of the Caster leveling list. Which currently is at:

Illya (Completed, except for skills)
El Melloi (at Level 43)
Lily Medea
Miyu
Nitocris or Circe

Seriously, I have way too many 4 -Star Casters. As is, I'm pretty sure I'll only use Miyu when I feel like running an Illya based team.
