I wonder, how to play Nosepass in NU ?
Because the Skarmory Counter is useless in this tier, a Steel-trapping role with Magnet Pull and EQ/FPunch is outclassed by Diglett Arena Trap (even by Trapinch Arena Trap), ...
Your opinions ?
Nosepass isn't worth using in ADV NU if that's what you're driving at. Theoretically, if you were to use to trap, its main niche would be to trap Mawile in NU, but it would probably lose most of the time if not all the time, so really its main niche would be to trap Lairon and Metang, but they are rarely seen so bringing Nosepass wouldn't be worth it. You'd be correct that it's outclassed by Diglett as a trapper, as it can take out not only the Steel-types, but the other prominent Rock-types too, as well as dangerous Fire-types like Flareon and other weakened Pokemon like Roselia and Plusle.
The Nosepass analysis on the Dex is from ~10 years ago and extremely outdated, but in fairness, it probably has more use in OU than it does in NU as it can effectively trap Skarmory (though Magneton is 10000x better at this role).
If you really want to use Nosepass in NU, it'd probably be best to make use of its surprisingly decent Special Defense to make it a mixed wall of sorts to wall not only the prominent Normal and Flying-types, but also an effective Fire-type check that doesn't just buckle to Hidden Power Grass unlike Sudowoodo and Graveler. So the best set would probably look like:
Nosepass @ Leftovers
Ability: Magnet Pull
EVs: 252 HP / 4 Def / 252 SpD
Sassy Nature
- Toxic
- Hidden Power Rock / Thunder Wave
- Protect
- Explosion
There's really nothing else for it to do lol, and even with this set it's completely outclassed by Magcargo save for the ability to use Thunder Wave and ability to not die completely horribly to Hidden Power Ground.
