ST 3star Archer

Robin for sure. His NP is incredibly powerful and works well with his skills. He can also act as an decent Crit Archer due to his A-rank Independent Action and has an evade with on demand stars and a form of sure hit. Use him in an arts team for maximum performance.

His only real competition is Euryale, who is only effective vs male servants, and Billy the Kid, who is all burst damage and slightly more unreliable due to his low NP and Star gen stats along with his quick-focused deck making him unable to spam his NP nor deal high amounts of base damage.

Lol is that even a question?😂😂😂the answer is robin,robin all the way....

Depends on what you need. I think it comes down to three choices.

Robin: Incredible nuke NP but weak regular attacks
David: Weaker NP but best overall utility in my opinion
Euryale: Amazing against male enemies thanks to her skills and NP

Actually, in the long run I hardly ever use Robin because he is pretty lackluster aside from his amazing NP. David's teamwide evade and attack-up skills are golden, so I still use him once in a while in really tough challenges. Euryale I only ever leveled and used in Camelot, but there she was pretty great.

Robin is definitely one of the better damage dealers, as long as you can trigger his NP on a target that is poisoned.

Euryale's target needs to be Male, so that one is harder to guarantee.

Another good option is David. He isn't quite as strong a damage dealer, but he also doubles as a support character because of his skill-set. He has Charisma to up everyone's attack, has a self heal and defense-up, and most importantly has a party heal that also gives a 1-time evade. Plus his NP can do skill seal, which can be useful.

Personally, I like the evades that are numbered and not timed, I feel like I always end up "guessing wrong" when I have one character do a 1 turn evade/invuln.
