Scrafty@Lum Berry / Life Orb
Trait: Intimidate / Moxie
Evs: 252 HP/ 252 Atk/4 Def or 252 sp. def./ 252 HP or 252 attack / 4 attack/def.
- Payback / Brick Break
- Dragon Dance / Bulk Up / Amnesia(?)
- Drain Punch
- High Jump Kick/poison jab
Because scrafty is pretty slow, he'll likely get hit first so now payback will now do 150 base damage instead of 75( STAB included, and 75x2 is 150). Brick break breaks screens and gets stab while having decent power.
Dragon dance/bulk up/amnesia: both increase this guy's attack and compliments moxie, but don't use dragon dance if using payback, as it increases this guy's speed, which is good for sweeping, but bad for payback. Bulk up if you like a tanky scrafty. amnesia + intimidate is a deathblow to attackers.
Drain punch: drain punch recovers some much needed HP, as scrafty runs low on this precious resource. Also has decent power, STAB, and recovers lost HP from setting up dragon dance or bulk up.
Hi jump kick/ poison jab: poison jab deals with fairies. hi jump kick has tons of raw power and STAB but beware of missing with this move.
Lum berries take out any status that might harm him during setup. Moxie makes this guy's attack crazy high and intimidate removes the need for ev investment in def., which frees up investment in sp. defence, and that's a good thing, when trying to kill nasty plotters/ high sp attack Pokémon or trying to survive an onslaught of their attacks. Amnesia isn't too reliable( although you can use it ) in my opinion because it only boosts one stat. Adamant boosts scrafty's attack to good levels, and a drop in sp. attack doesn't matter, as he doesn't use this stat much. Life orb is a staple in any attacking set. All in all, scrafty is built to be a hard hitting tank, but be careful, as this guy isn't fool proof.
Hoped this helped:)
