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.
