Haven't used it in a little bit with all the new toys, but I have fun with this. Very customizable for what your team needs. With Grassy Seed active, you can go toe to toe with a Kingambit even boosted with 5 SO. You may not even need to Tera if you catch it early enough!
First half of the set was once featured on a Grassy Terrain Drifblim set on Team of the Month a little while ago. The second bracket are my edits. Drift is extremely customizable, and having T Wave, WoW and Hex made it a very potent team player. I didn't realize how useful status and support moves were on an Unburden mon. Obvious weaknesses, hard walled by normals...but you aren't using the set for that. Still, I reccomend Calm Mind and one other.
