Jolly Nature
- Swords Dance
- Close Combat
- Iron Head
- Stone Edge
Thanks to the many resistances/immunities provided by its typing, Cobalionis able to use SD once (or even twice) and, then, it is able to clean the opposite team despite its mediocre base Atk.
The remaining three slots are for three attacking moves, with two of them with high base power.
The EVs spread is a simple offensive one.
Lum Berry is here to fix (mainly) burn and paralysis that ruins our Cobalion.
Team(mates) support
A slow VoltSwitch support is appreciated to put Cobalion onto the battlefield without taking damage: this way you are able to force more switchouts, and these extra free turns can be used to set-up for free.
Spe control is always appreciated because a base 108 Spe is good, but not spectacular.
