Highly doubt this sees UU play RU at most.
I agree with this.
Its stats are comparable to Rampardos.
145 of its highest offense versus 165 for Rampardos. 77/90/75 bulk versus 97/60/50. 43 Speed versus 58.
0 SpA Mew Psychic vs. 0 HP / 0 SpD Rampardos: 169-199 (50.4 - 59.4%) -- guaranteed 2HKO
0 SpA Mew Psychic vs. 0 HP / 0 SpD Vikavolt: 123-145 (41.6 - 49.1%) -- guaranteed 3HKO
0 Atk Mew Psycho Cut vs. 0 HP / 0 Def Rampardos: 114-135 (34 - 40.2%) -- guaranteed 3HKO
0 Atk Mew Psycho Cut vs. 0 HP / 0 Def Vikavolt: 84-99 (28.4 - 33.5%) -- 0.1% chance to 3HKO
It looks like Vikavolt will be a little bulkier, but obviously weaker on offense.
Its typing is arguably better than Rampardos' given that it's almost guaranteed to take a hit, and its ability does allow it free switches. However, it doesn't get Sheer Force. For all the people talking about Agility, Rampardos gets Rock Polish, but that hardly ever gets used unless it's carrying a sash. Honestly, I don't think it's different enough from Rampardos to be played substantially differently, and Rampardos is PU.
I really had high hopes for this thing, but it looks like it's a dud.
Edit: It's actually even worse for PU-Vikavolt than it looks. Below are all of the
A-Rank Viablilty PU mons which Rampardos outspeeds and Vikavolt doesn't. I didn't bother looking beyond that.

Even assuming they had the same damage potential, the difference between 43 and 58 speed is huge. Vikavolt will struggle.
