I mean, Revenge is pretty great against Byleth for what it applies to; Byleth is absolutely one of my preferred opponents with Incineroar. But for Sephiroth Revenge is also a factor in his recovery and Shadow Flare, and Sephiroth's game is more dependent on being proactive. Incineroar is my best-perfoming character against all sword users in the game, so enjoying him against Sephiroth isn't much of a surprise to me.This post is honestly what I'm talking about. I have an extremely hard time believe seph won't demolish incenaroar when he becomes more polished.
For instance a 50 50 of dash grab or dash attack for sep particularly with owa active is something people aren't really ready to implement yet and the zoning tools and other parts of his kit are heavily underemployed. Revenge has not proved to be an issue for characters like byleth or min min because as they became optimized incenaroar weak eases and slowness began to show its fatal flaw.
(That said, my Mac is definitely doing better against Sephiroth than Incineroar for the very small sample size we have.)
As for Min Min, Revenge would be great if she didn't have 2 arms. As it stands, it's one of the worst matchups in the game for it, and contributes to it being one of Incineroar's worst matchups. I would never play Incineroar into Min Min.
