Taunt BU
Urshifu @ Black Glasses / Lum Berry
Ability: Unseen Fist
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Bulk Up
- Taunt
- Wicked Blow
- Close Combat
So the main way slower teams are dealing with Urshifu is with MandiPex, which Taunt just shuts down entirely by disabling Roost/Recover, as well as Haze on Toxapex. From there, the only thing that MandiPex can do is hoping for a Scald Burn (which you can run Lum Berry for if you wish). Taunt also prevents another counter in Tangrowth from putting you to sleep (be careful of Focus Blast though).
