Well, if you really insist, here’s a short list:

-Euryale, and other strong ST Archers.

-A strong Saber (preferably ST, but Mordred/Siegfried work well, too)

-A good Assassin (such as Shiki or Jack)

-A strong Rider (Kintoki Rider works well)

If possible, preparing a good Berserker or Avenger with good support will also make a couple of boss nodes much easier as well.
