Surprised not to see a Z-celebrate set here.

Victini @ Normalium Z
Ability: Victory Star
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Celebrate
- Stored Power
- Searing Shot
- Hidden Power [Ground]

• Celebrate: Z-Celebrate causes all stats to increase by 1.
• Stored Power: (20*6)+20= bp 140 and stab.
• Searing Shot: good stab, higher chance to burn than Fire Blast/Flamethrower.
• HP Ground: covers everything else that resists fire and psychic.
