Guide
This is a jungle build. Go with will-o-wisp first, because it just does more damage. Lick is cc for the blue and red buff mons, while helping with the corphishes. Stacks aren't that easy for a jungle mon, so recommended specs + wise glasses. Eject button to well, eject away!
When you battle an opposing pokemon, use dream eater's first use and then shadow ball then use the second use, for maximum damage output + healing + cool down reset for eater (if you ko, which you most probably will.) Use phantom ambush to either steal bosses or chase down low hp opponents. Although you wouldn't want to waste it on something like eldegoss.
