Gorebyss should move up anyway, because you can also surprise your opponent and use it as a standalone sweeper with Smash, Surf, Ice Beam, HP Grass/Substitute, and it's pretty damn effective in that role as well. Base 114 SpA is excellent, it reaches 446 speed after a smash (which is enough to outspeed things like Adamant Scarf Ape, Jolly is pissweak) and it has pretty decent bulk too with 55/105/75. Behind screens, it's virtually unstoppable, but it doesn't necessarily need them either. It's the most versatile Baton Passer due to having access to almost every boosting move you can think of and only has 2 weaknesses.
Also, for those saying "You can only pass with Gorebyss once", if you're doing it right, that should be enough to win you the game most of the time anyway, and I've passed more than once with Gorebyss on several occasions as well. Since it has pretty good natural bulk, even at -1 you can usually survive a hit and pass into something which resists the moves that the threat in front of you has. There are also quite a lot of defensively inclined pokemon in the tier which Gorebyss can set up on a second time. Also, when using Gorebyss to Pass into Xatu instead of Combusken, you free up a move slot to run Substitute instead of Calm Mind, which helps prevent crits, secondary effects and moves like Dragon Tail from screwing you over, and allows you to avoid Sucker Punches.
Not moving it up would be crazy, as it, along with Combusken, is starting to define the meta, and they are both amazing forces which should be at the top of any teams priority list. Gorebyss for A.
