Night Strike: Slashing moves gain priority
*Pokemon with Intelligent Agent change their stats accordingly:
>Physical attack: +1 attack
>Special attack: +1 special attack
>Status that targets the opponent: +1 accuracy
>Status that targets self/partners or field condition: +1 speed
>Trick Room: -1 speed
>Status that heals self or partners: null
Each boost only works once; knowing two special attacks won't increase special attack by 2, etc.
I know Prevos don't have Mega Evolutions, but since they operate so much differently than what they evolve into, and were final evos at one point, i couldn't resist.
