can E0S1 Archer clear any of the knights?

my team is E0S1 Archer/E0S1(Sunday LC) Sparkle/E1S0 Robin/E0S0 DHPT. he worked wonders the past two AA but it seems i’m way off in this one, couldn’t even 2 star K1 or K3.

i’m gonna be honest i also don’t know how Robin should be played with Archer, i just grabbed her E1 after hearing it’s good in the Archer team, but the rotations feels weird and clunky. also should Sparkle still be on Eagle or should i change into Sacerdos?
