I'd pick;

[Lancer] Artoria Alter, because you lack a offensive Lancer.

[Assassin] Wu Zetian, because you lack a offensive Assassin. And/or [Assassins] Emiya or Carmilla, for the same reason.

[Caster] Medea Lily or [Rider] Saint Martha for a party-wide debuff cleaning and healing.

A [Berserker] between Penthesilea, Lancelot, Ibaraki Douji and Tamamo Cat - Or [Berserker] Heracles, if you are willing to level his bond.

I think you are better off not picking a saber since you already have three of them.
