Title.

For me, it'd be Beautifly.
I was amazed by how good they turned out to be in ORAS Nuzlockes with access to Gust, Absorb (and stronger variants), and Quiver Dance. Unfortunately I could never keep one alive until the end of the game in any of my Nuzlockes, but one survived past Winona and then got killed by some NPC. I'd like to think I've gotten much better at this stuff so maybe the next time they'll survive past the E4, it could happen.
