Okay, let's do this.
Krookodile
Krookodile can absolutely MURDER with this:
Krookodile (M) @ Choice Scarf
Trait: Moxie
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Earthquake
- Rock Slide
- Crunch
- Outrage
Typical sweeping Krookodile. This can even be used on Hilda's/partner's Pokemon for a knockout, massively raising attack. Crunch and Earthquake is STAB, Outrage is just freaking powerful, and Rock Slide deals with Ice types.
Lucario
No point in putting a physical move when you have Modest. If you want priority, go with Vacuum Wave:
Lucario (M) @ Life Orb
Trait: Steadfast
EVs: 4 HP / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Dark Pulse
- Nasty Plot
- Aura Sphere
- Vacuum Wave/Psychic
Nasty Plot makes Lucario into a power sweeper. Aura Sphere is STAB, Psychic and Dark Pulse are coverage, and Vacuum Wave is priority.
