As we're doing a UM ccat, I figured it'd be fitting to not just do a cool 1v1 mon, but a cool 1v1 mon but one that isn't good in any other UM tiers! (that's what a lot of people are suggesting too here so ye)
I thought about a few mons that I've enjoyed using in 1v1 that fits these conditions! A few that do that I thought of were
-Granbull
...just granbull
Granbull @ Choice Band
Ability: Intimidate
Tera Type: Fairy
EVs: 88 HP / 168 Atk / 252 Def
Adamant Nature
- Play Rough
- Counter
- Ice Punch
- Wild Charge/Fire Punch/rock slide/really whatever you want
This is ev'd for choice Band Hoopa-u after intimidate, as well as choice Band urshifu-rapid-strike, with the rest dumped into attack!
I've used this in a few individual tours, as well as world cup of 1v1, and although it usually works as a good second/third mon, I've built around it with success!
While not a top tier mon, it currently sits around D rank in the VR (I think it has potential to make it to C-, even C!) and is a physically strong and physically bulky pokemon that gets little to no 6v6 usage!
Calling all granbull believers!

Here is an example team. Although it does struggle against some ursalunas (and admittedly a lot of other mons), I think that as a community, we can create an actually decent granbull team :)
