Guide
So as a phantump you just will-o-wisp all you can until you evolve. When you're a trevenant with wood hammer you are basically invincible cause you can just literally wood hammer everything that tries to stop you but when you get horn leach you can truly start sweeping the opposing team.
With a goal-getter,wood hammer and horn leach, you can pretty much do anything on the other side of the field so yeah, you can sweep with this trevenant build.
