Something that I've noticed with the team is that, while it has most of its bases covered, it feels a bit too reliant on positioning for a Mega Gengar team. Though it has all-around good Pokemon that can take hits and punish, it lacks that one hard hitter that can instantly delete threats at a moment's notice; this is especially relevant as the team has an Eject Button Amoonguss, as it lacks that go-to hard hitter that can come in to wreak havoc on general cases.
Enter Terrakion; with its satanic Life Orb Close Combat and a Speed tier adequate for the job, Terrakion can be a serviceable point-and-click killer after a good trap or so. Its ability to instantly apply pressure and collect can prove to be quite handy with Mega Gengar, especially as it can unleash its CC or clean up chipped foes with Rock Slide without fearing an oncoming Intimidate. Its presence can be quite useful against Mega Charizard, Volcarona, Heatran, and Hydreigon; its being a non-locked physical attacker also helps against Sylveon and Mega Gardevoir, granting the team more flexibility when it comes to handling those Fairy-types. As a bonus, its access to Quick Guard can surprisingly come in handy against the likes of Talonflame and Thundurus as well as for acting as a buffer against Azumarill should that match-up ever go south.
The team lacks switch-ins to Dragon-type which blows still, but that can be overcome by offensive pressure I suppose; Latios, though a sketchy foe, isn't as common as it is and can be managed by Mega Gengar, while Hydreigon can be handled by Terrakion. While the last slot could be a defensive answer, I feel overall that it's not worth it as patching that hole up would be inefficient if done with solely the sixth mon; it'd be better to push to a more offensive direction, nifty for both the Dragon match-up as well as the Mega Gengar synergy.
