From my roster, you can see that I am totally a F2P player (didn't even roll for the GSSR) and I'm saving quartz to get better servants. I'm wondering what upcoming banners that you can suggest I should roll for this 2019, based on my current Servants. Here's my roster:
Sabers: Musashi, Lancelot, Saber Liz, Siegfried, Nero, Bedivere and Caesar
Archers: Archer Altria, Kuro, Emiya, Robin Hood and Arash
Lancers: Altria Lancer, Tamamo Lancer, Liz, Jalter Lily and Cú
Rider: Martha, Santa Alter, Marie Antoinette and Medusa
Caster: Merlin, Halloween Liz, Caster Gil, Medea, Hans and Mozart
Assassin: Kiritsugu, Kojirou (Currently lvl 92 still waiting for grails to lvl 100), Sanson and Jekyll
Berserker: Kiyohime
I got those SSRs with pure luck ._. Thanks for the suggestions in advance!
