[REQUEST] GENGAR VGC TEAM!!!

[BVBlair]

Hey guys, I have been getting into the competative battling for a little bit now. I have various teams but none that I love. I am missing that one thing, GENGAR.
If anybody can help building a team around Gengar then please feel free to help me!! I would love to be able to do VGC or Singles with Gengar.

Thank you! >.<

It's basic and not very strategic,  but my versatile Gengar has Shadow Ball, Giga Drain, Thunderbolt, and Dazzling Gleam.

I paired Ghostium Gengar with Scarf Lele to counteract Mimikyu+Hariyama knowing well how damn strong is that core. Than I added NP LO ARaichu as Terrain abuser, and Tapu Koko as option to Lele's one. Finally I added Garchomp because it works well with Lele, Koko and ARaichu hitting hard AMuk and Kartana. Gyarados is almost a filler, bringing in my team a Ground immunity and Intimidate. I choosed physical Koko to KO Nihilego more easily and with Sky Drop he gives Gyarados and ARaichu nice situations to setup. I give Garchomp Dragon Tail as only way to deal with P2's TR and Rock Tomb as Speed Control form.
