Is Urshifu R totally outclassed in the meta?
It's just overall kinda mediocre. CB struggles to break stuff like Pex and Fini and is really prediction reliant, unlike the Single-Strike form, which could blow past almost anything in the meta with Wicked Blow+CC+Poison Jab before NatDex banned it, and other stuff like Scarf and BU + Z-move is either outclassed by other mons or just not worth the effort for supporting it. You could attempt to run it alongside Future Sight Slowbro to break Pex and Fini, but opposing Slowbro are still an issue, and there are better options for Fighting-type + FuturePort like Mega Lopunny, Mega Medicham, and even the occasional Galarian Zapdos. Hope this isn't too long of an explanation and that it answers your question!
