► For Gurdurr I decided to go with one of the most intuitive cores for PU ever. With
Mesprit, not only do you have a great defensive backbone to check the whole physically offensive metagame, you form an offensive core that is very annoying to beat. But let's go in detail!
@ Eviolite / Guts
252 HP / 44 Atk / 212 Def /Adamant
- Drain Punch
- Mach Punch
- Knock Off
- Bulk Up
► Gurdurr only has two sets in the current metagame: Bulk Up or Toxic. For this core, Bulk Up is the best way to go. The reason is being explained in the Mesprit paragraph.
Gurrdur is able to beat many of Mesprit's checks: Skuntank, Sandslash and Audino for example.
► Defensively Gurdurr helps Mesprit to take on threats like the 2 Normal types (Kangaskhan, Stoutland), as well as the two Rock types (Lycanroc, Aggron).
@ Colbur Berry / Levitate
252 HP / 240 Def / 16 Spe /Bold
- Stealth Rock
- Psychic
- U-turn
-
Healing Wish
► Mesprit on the other hand supports Gurdurr defensively because it can pivot into Psychic Type attacks and one Flying STAB (coming from Dodrio, Oricorio, Swanna and so forth. But only once ofc).
► On paper, it doesn't seem impressive when it comes to the things Mesprit can take on for Gurdurr but the reason I chose it anyway is the following: Healing Wish is so nasty to deal with when combining it with Buln Up Gurdurr. Gurdurr often comes into situations where it takes percentages over percentages to deal with mons (Kangaskhan, Stoutland, (sometimes) Dodrio, Kabutops, Primeape, Skuntank, Golurk...).
► All of those mons are 1v1ed by Gurdurr but all of them do chip damage that heavily pressures Gurdurr because of it having no passive recovery in Leftovers.
► Additionally, dealing with 2 Gurrdurs that tried to setup (thanks to Healing Wish) in one battle is so hard to deal with if you don't have enough fighting resitances.
► If you ask me, that core alone is the reason I don't leave the teambuilder without having at least two good Fighting resists. So in conclusion, Mesprit is the best partner because of the impact they have on the metagame.
► If I had to build a team with those two, I'd personally slap
Toxic Skuntank on there. You need a switchin to Mesprit - a way to kill it especially, as well as a way to pressure Silvally-Fairy, Clefairy, Jellicent and
Quagsire. The latter one is the reason I'd put use Toxic Skunk. Why that Pokemon works well with Gurdurr in general can be looked up in
