What team comp should I use?

If your willing to upgrade Emiyas Hawkeye and max Hans's skills and have a 2030 CE then I'd suggest trying out using emiya Hans and waver as support(with Hans and waver with 2030) it's a monstrous trio, if you use all their crit skills in one turn ( on emiya) you can get his critical damage up to 290% for 3 whole turns, not including wavers team damage booster skill (also lasting 3 turns), it's a really great fun comp, but you'd need a lot of ascension mats for Emiyas Hawkeye but it's worth it,even better if you have a CE boosting crit strength for him. The 2 2030s will give you 16 crit stars passively each turn and then Hans innocent monster will give you some when active too so crit stars won't be a issue

A Lot of your servant is considered premiere, good luck on raising them.
Also what surprise me the most is, you have both the Broken servant from the Art side and Buster side.
Most of them also raised decently, maybe this will help your planning a bit better.

I also agree with Emiya and Hans, then i'll proceed to another servant.
Helena can be a generalist supp along with Waver. For more durable Crit supp Marie Caster is a decent choice.
Mozart and Shakespeare have very strong steroid, which will make you can dish out more ridiculous damage. With your very strong damager technically you can One Shot lots of bosses and enemy, of course with the help of Supp.

You want some more buff stacking servant for your beloved DPS ? sure
Caesar, 3 damage increase skill with only low CD.

One example, Jalter/Raikou/Rama/Ozy/Brynhildir Joint Recital/Victor of the Moon/any Buster CE + Waver 2030 + Hans His Rightful Place + Leonidas/Mashu ( ST/AOE NP taker ) + Caesar/Shakespeare + Backup DPS/Last Man Standing.

Use Anniversary Blonde for short fight and Battle suit for harsh battle ( also good for buff stacking for further damage increase ).
