Assuming you mean fighter duelists, I would go with Hybrid Kayle, she can shred your defenses, nail you with both forms of damage, and then her Ult can block either a very hard hitting spell, or sustain her in the buff of Rageblade so she can just heal to max by hitting you and her heals.

If you want a beefier fighter then I would say Olaf, He can wait for your CC and hard hitting spells to go then ult and tear into you like you are made of ricepaper.
