Servants of two different timelines do battle in the arena. We're using the general visual novel/light novel versions of all characters (because the anime version of the Apocrypha servants would steamroll the opposition, except for maybe the caster fight). Assume that they all have equally good masters but no command seals will be used.
Most of them will be matching servant classes except for the last one for what's probably obvious reasons.
Archer fight: Atalante vs. Emiya
Berserker fight: Spartacus vs. Heracles
Lancer fight: Karna vs. Cú Chulainn
Rider fight: Achilles vs. Medusa
Saber fight: Mordred vs. Artoria
Special fight*: Semiramis vs. Medea
*Semiramis is as powerful as she would be in her throne room and Medea is as powerful as she would be in her temple in F/SN
