Delphox @ Leftovers 
Ability: Magician 
EVs: 24 HP / 252 SpA / 232 Spe 
Timid Nature 
- Calm Mind 
- Shadow Ball 
- Flamethrower 
- Grass Knot 
CM + 3 Attacks Delphox! The idea here is to send Delphox in on something that doesn't want to take a fire attack, like Escavalier or Abomasnow, to force a switch, and set up a Calm Mind to boost your special attack and special defence. Then from there, the combination of Shadow Ball/Flamethrower/Grass knot has perfect neutral coverage, allowing you to blast whatever's in your way!
