One of my Favorites! Although not top in the chart...
First time posting a moveset, I'll try my best tho.
Agressive Suicide Physical Sweeper
Kommo-cidal (M) @ Life Orb
EV Spread: 252 Atk / 252 Spe / 4 Def
Nature: Adamant (+Atk/-SpA)
- Swords Dance;
- EQuake/Rock Slide.
This set foccuses on going in, taking 1-3 enemies and then retiring, a reason why I maximized Atk and Spe obviously, you want to act first, take advantage of the solid Atk Stat he has, Buff it up with a Single Swords Dance and then select a Outrage for a STAB, Reversal for a Stab when low HP and EQuake for covering Electric Types or Rock Slide for Flying, although he shouldn't have much problem at KO'ing anything after he gets one Swords Dance out as his damage skyrockets. Bullet Proof is to protect him from some moves that could cause trouble, Overcoat if he is in a Weather Comp (Which should not be the case actually in my honest opinion), Soundproof should be kinda disregarded as there is not much "sound" moves in the game that are abused, but it's always an option too.
Kommo-o (M) @ Weakess Policy/Leftovers
EV Spread: 252 Def / 252 SpD / 4 Atk
- Dragon Dance
- Brick Break / Dragon Claw
- EQuake / Rock Slide.
Careful nature for more SpD, which is to balance out his defenses, Weakness Policy is amazing to keep his offensiveness if you wish so, he becomes a great wall with a high damage output, slower than normal, but when he hits oh boy it hurts, Brick Break for passing through Protects and those kinds of stuff and Dragon Claw for dealing with other Drags and having another STAB, Counter is a great move overall, and as you probably won't go to low HP lands too much with this EV Spread then you can use more Counter's, Reversal is only good if you often find yourself with Low HP obviously and that is something that happends A LOT if you run the first Set, EQuake and Rock Slide for same reason as before, coverage, Dragon Dance here is better than Swords Dance, as you can often get 2-3 of these and go for a high Damage, High Speed and High Resistances Kommo-o, you basically get all the stats you need to survive and act fast while dealing damage. I put Leftovers for the item there for those who want consistency, it's not always that you'll get hit with a Superefective move to activate Weakness Policy, but I personally prefer the damage over the Sustaining Capacity, taking other Supportive Healer with you helps at staying long periods in the fight and building up Dances to come out and deal a mass of damage, sometimes even OHKO'ing enemies or 2HKO'ing them with DC or Brick Break/Counter.
