What? Tyranitar and Bisharp are great!
Replace Houndoom and Scrafty for them. Give Stealth Rock to one of your Pokemon, because Entry Hazards and good. But the catch is here -- Bisharp should have Defiant. When you set up Stealth Rock, an opponent will try to use Defog. Switch in Bisharp on this predicted Defog to double its Attack, because Defog reduces Evasion!
Tyranitar's self explanatory. Give it a Mega Stone and Dragon Dance, but only boost late game, because opponents can deal with you early game. Tyranitar is almost impossible to defeat late game, when all its threats are removed, so it can sweep with Dragon Dance!
And replace Drapion for Mandibuzz. Drapion is quite bad, and Mandibuzz can easily deal with most Fighting Types. Use a Roost, Defog / U-Turn, Knock Off, Foul Play set. Foul Play can easily beat Fighting Types, who have high Attack stats, even though it's resisted.
You could also consider SubPass Mega Absol with Sucker Punch and Play Rough, a very annoying set. Mega Absol is fast and can deal with Fighting Types with Play Rough, and it can set up Substitute on a predicted switch or against a defensive Pokemon, then Baton Pass to something else as needed! It has Magic Bounce, too. If you use this, still use Tyranitar, but don't give it Tyranitite.
Sabeleye is awesome. Use it.
Give WishPass to Umbreon just so it can heal others' HP. And Heal Bell, too, so that it can heal status.
That's all great advice... I think it's settled. I'm going to EV train all of those Pokemon. I still need Sableye and Scrafty (I'm waiting on a reply from AYerrowDocta to see if he can get me those). I actually already have an EV trained Absol, but I need to know if the person I trained it for still wants it (I trained it for him in W2 almost 6 months ago). If anybody can get me a Larvitar with good EVs, it would be greatly appreciated. Vullaby, too.
Umbreon... Both Wish and Heal Bell are both egg moves, so I didn't make AYerrowDocta go through the trouble of getting them for me. Unless someone can get me an Eevee with both of those egg moves and a Calm Nature, then I can't use that set.
It's my particular Bisharp that isn't so good... What's a recommended move set?
