I have 3 months playing and now I'm triying to pass London, I have no realy much problems on it but I have some stored archer and Zeker cards that I want to use.
I already have Euryale at lvl 50 and also have David (1 copy) and Robin (3 copies). I was waiting to have the 5 copies of Robin to powered up it but I need to use those gold cards.
Wich I should powered up David or Robin, My team is focussed in Arts I have Tamamo, Bride, Shiki (assassin) and also Euryale.
Or use them to powered up my other servants
Robin Hood is considered one of the best servant with single target NP which is an Arts NP also.
David, in the other hand, is a good support for the team with healing and evade for everyone.
So it is up to you but if you lack a good servant in another class, you should power him (her) up.
