Mega Drampa Doubles Team Discussion

Hello guys. So I've had this idea of making a mega drampa team (doubles ofc) with the main point being debuffing the opposing team and healing to potentially activate berserk multiple times. Kinda like how terapagos teams used to tend to extremely supportive archetypes treating it as the main wincon? Something like that. I've had the problem of actually choosing a moveset for my drampa because there's a big 4mss right there (hyper voice, snarl, hwave/flame, tect,roost, cm). Also I find the lack of items, well... Kinda flabbergasting so I'd like some advice on what to run because it seems kinda scuffed. Any complex EV suggestions are appreciated since I gotta do that sometime. So here's the 6 I've been having in mind. Any help appreciated.
