Saber Best Teams
Saber — Trailblazer (Ice) / Tingyun / Lynx
A common Saber core: Saber as Main DPS with two single-target/support buffers and a sustain. Remembrance Trailblazer and Tingyun are standout supports (True DMG buff and energy restoration respectively). For F2P flexibility you can use any two supports that provide buffs that only target Saber.
Saber — Sunday / Robin / Huohuo
Best-in-slot style team where supports focus on energy restoration and turn-advance. Sunday and Robin cover turn-advance + single-target buffs; Huohuo shines as the sustain/energy+ATK buffer for the party.
