Pokemon with good synergy with Mega-Gengar?

I just need any one Pokemon (preferably a physical attacker) which works well with M-Gengar.

Mega-Gengar is less about synergy and more about clearing the field for one of your sweepers. As ReadyAimFire stated in his comment:

You don’t need good synergy. You just need something that HAS to getrid of something else, so if you were using say Groundon, you’d add inMGengar to take out Kyorge for example.commented 4 hours ago by ReadyAimFire

So if you have a team consisting of Mega-Gengar, Xern and four others, then you’re using Gengar to eliminate any checks or counters to Xerneas, such as Bronzong, Jirachi, Scizor etc. Mega-Gengar will not be switching into very many attacks at all (like none because just about everything neutral+ 2HKOs it) so you’re less worried about synergy than you are about your sweepers and if MGar can really support them well. Generally you want sweepers that require little set up such as EKiller, GeoXern, Calm Mind Kyogre (Once it’s counters are cleared it’s easy to set up), Dancing Groudon, and so on.

If you’re asking about in-game ignore what I said and use whatever Pokemon you think is cool 0.0!

Welll a good teamate for Mega gengar could be honchkrow

Honchkrow can be physical or special(in your case physical)

It resist or is immune to all of Mgengar weakness .

Now for a movesetHonchkrow@(any item)Ability: super luck(for the high chance of crit) or moxie( K.O 1 Pokemon and let the sweep begin)Nature: jolly/adamantEv252 atk/ 252 speed/4 HP-night slash-brave bird-super power-tailwind

Now special

Honchkrow@leftoverNature: modest/timidEvs: 252 Satk/ 252 speed/ 4hpnasty plot(power up)tailwind(allows him to outspeed almost any thing)dark pulse(STAB and chance of flinching)heat wave(deals with anything else because of high power. covers ice)

You could probally find better moveset but these are some I found pretty good

Hope I helped!
