Muscle bug isn't even ranked in the vr. This makes sense given that the top threats include sword Zacian and Yveltal, all of which have super effective moves that rip apart Buzzwall's biceps. That's not even counting how Mega Rayquaza just deletes it out of existence
Also, Buzzwall's typing is also a reason why Pheromosa isn't that great in ubers, it's almost an invitation for Xerneas to come in. Well, more like begging Xerneas to come in actually especially if they don't have poison type coverage, if they even get any in the first place
