Failed to land a Scathach on my first 10x Summon. Got a Trap instead.
edit-
* Aya Reiko plonks down the $80 for the max quartz package
10x Summon 2: Martha
10x Summon 3: Siegfried...
Silver Lancer... *zap* Turns Gold... Liz
10x Summon 4: Gold Lancer right off the bat... SCATHACH!!!
Now I have...
2 Gold Sabers (d'Eon and Siegfried)
3 Gold Riders (NP2 Iskandar, Astolfo, and Martha)
1 Gold Caster (Helena), I'm not counting Iris since I can't ascend her.
2 Gold Lancers (Scathach and Liz)
2 Gold Assassins (Shuten and NP2 Emiya (Asn))
1 Gold Berserker (Tamamo Cat)
No Gold Archers. Guess that makes my choice of a free 4* servant easy.
