Just wanted to point out that Flame Orb is strictly better than Toxic Orb on Guts sets since the burn nerf to 6.25% damage.Instead of using Normalize, you can use something like Adaptability, Tough Claws or Sheer Force to gain power without missing coverage. Hustle + No Guard also works if you have low accuracy Physical Attacks like High Jump Kick, stone Edge or Dynamich Punch.
Here i drop a wall breaker dedicated to break stall teams
Hoopa-Unbound @ Toxic Orb
EVs: 4 HP / 252 Atk / 252 Spe
- Hyperspace Fury
- Toxic Boost
- Dark Aura/ Quick Feet/ Defiant
With double boost from Toxic Orb and Dark Aura, you can 2hko Clefable and OHKO everything else besides intimidate stuff. You can use Defiant to nail Intimidate users but you will have less power overall and your matchup against Clefable will be tougher. If HU gets an intimidate drop, switch it out because you need every Hyperspace Fury to hit with all its fury before it rans out!
Quick Feet is better ability in general, but against stall you will need every bit of power you can get.
Azumarill @ Leftovers
Ability: Sap Sipper
EVs: 252 HP / 4 Def / 252 SpD
- Perish Song
- Mold Breaker
Stall breaker Azumarril. Mold Breaker and Soak helps you trapping Sableye Mega
EDIT: I totally missed Toxic Boost.
