Set out Luna, and mark Maeve so Luna can rush and stun her. Even with the stun gone, keep her marked because Luna can still deal auto-aim attacks to Maeve. Though once your fox is dead, run away. LUNA counters Maeve, not you.
Pretty close battle, but the advantage goes to Tiberius simple because Tiberius has more burst than Maeve with combat trance. Maeve still has a fighting chance though because she has a smaller hitbox, and she's more mobile than Tiberius.
