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

Which side gets the most wins?
