Mawile resists every move Gothitelle usually has, save for HP Ground as I mentioned. With its maximum attack stats (Boosting nature, Life Orb, Sheer Force), it rolls on Gothitelle with Crunch (53% minimum, guaranteed 2HKO), and takes on Linoone with heavy resistances and a powerful Iron Head, which is a guaranteed OHKO after Belly Drum and a 2HKO, possible (35%) OHKO without.
You certainly are great with obscure (unseen) Pokemon, and I think we all know that by now.
Anyway, let's see here. I think Scraggy can be decent, just for the fact that it can take out Psychic and Steel types, while being a threat to the rest of the team if it is allowed to set-up. It is, again, another pokemon weak to fighting that is helped by Gothitelle.
As stated, Payback can be used to stop Gothitelle's fellow Psychic types, while also scoring notable damage on Ghost types which are also super effective. Crunch can be used, but Scraggy only has 132 speed. Drain Punch hits steel types pretty well, allowing Gothitelle an easier sweep. It can Rest off the damage it takes, so it can continue it's sweep (Shed Skin stops rest), or have enough hp to switch into an attack against Gothitelle and Bulk Up/Retaliate.
Scraggy (F) @ Eviolite
Trait: Shed Skin
EVs: 252 HP / 4 Def / 252 SDef
Careful Nature (+SDef, -SAtk)
- Bulk Up
- Drain Punch
- Payback
- Rest
This set is also a decent Counter if Gothitelle is not running
Trick or
Hp Fighting. If neither are readily available, it can Bulk Up all over it, take it out with a few boosts (I dunno how many) with Payback, resting off any sustained damage.
Ill edit in something in a minute, I have to check something.
Edit: Okay, I was thinking about Weezing. But :L
