Predicting double switches. As I said, you have to predict an incoming MGengar and switch to your counter-pick simultaneously.
Or, Mega Gengar comes in with Volt-Turn, Baton Pass, or Revenge kill, and you're just hosed.
And, I'm sorry, but "predict perfectly is the
ONLY way to stop it" is pretty indicative that it's broken.

Yeah, okay. That's what the scout/phazer is for, as it finds out what MGengar aims to counter, which also gives the scout/phaze player some information on the rest of your team's sets.
Noting that each time you try to scout/phaze, you're taking damage from a not-inconsequential 170 Base Special Attack, and quite possibly losing your scouter. Again, assuming Mega Gengar
lets you scout it.

Actually, MGengar switches on the third Perish turn in order to not be KO'd by his own Perish Song, and the opponent can't switch because Shadow Tag is in effect. The way Shadow Tag works, it disallows the player from even choosing to switch, so you can't even elect to try to switch on the basis that MGengar will switch out. Now, if a patch was released by GAME FREAK/Nintendo that changed this to allow the player to choose to switch regardless of whether it will necessarily work, Perish Trap in singles would be finished.
Which wouldn't happen. Seriously, it's just not. Any time you attempt to switch while Shadow Tag is up, you would be wasting a turn, because there's no way to both try to switch
and do something else. Anyone who forgot they were up against a Trapper (any Trapper, not just a Shadow Tag trapper) or forgot they were in a trapping move would lose turns. While the competitive demographic may find it helpful, it will just frustrate and drive away the majority of the Pokémon fanbase.
I suppose I must agree, however, that MGengar's presence in a match vastly changes the pace and playstyle of the match on both sides, as letting it deploy successfully can be game-ending. I think, though, that there is a possibility that MGengar can be beneficial to the competitive scene. Yeah, okay, laugh all you like, but hear me out first:
You can't
stop it from deploying. Again, Volt-Turn. Baton Pass. Revenge Kill. Even if you can stop cold switches, Mega Gengar can come in and do its job.
MGengar is essentially the single most anti-meta thing ever to exist. If you want to survive/mess with teams running MGengar, you will have to run unpredictable sets. MGengar wants to snipe a foe with a particular role on the team, a particular set, but most often relies on the target's typing to do so. If you can run those same sets on the wrong Pokémon, MGengar's nicely customised moveset might turn out to be completely ineffective. MGengar can end up taking out a target Pokémon, only to be revenge-killed and then find out that that Pokémon wasn't running the set Gengar wanted to counter, but a different Pokémon on the team was. Pokémon that fill a particular role with an unusual typing but end up UU/RU/NU due to being "suboptimal" in that role can suddenly become OU-viable because MGengar fails to predict them. If this tactic is sufficiently successful, MGengar will see less usage while at the same time the tactic becomes universal; the relative "suboptimal" nature of these sets ceases to matter as many different Pokémon see common distribution because MGengar cannot predict this many different viable sets. The previous domination of a few select Pokémon due to their stats and relative comparison to "other Pokémon in the metagame" ceases to exist as that list includes 200+ Pokémon.
TL;DR version: Mega Gengar encourages people to use obscure Pokémon from other tiers, which in turn encourage even more obscure Pokémon to be used. Smogon OU collapses in a fairly spectacular manner, and Mega Gengar ceases to be an overpowering threat as its success depends on there being a very limited number of "viable" counters to any particular core. Not as likely as I wish it was, but still possible.
This is the
definition of "too centralizing". It's also the single
WORST thing that could happen to the metagame. As much as I loathe the metagame for various reasons ("slapping on Double Team and hoping your opponent misses" is nothing but luck based non-strategy, yet doing the exact same thing with Focus Blast or Hydro Pump and hoping they hit is a "calculated risk"? I think we'd see a rise in No Guards, Keen Eyes, 100% accuracy moves, and Always Hits moves, while at the same time seeing a
severe drop in 90-% accuracy moves, and therefore OHKOs and Hyper Offense if we allowed even a single stage Evasion boost in battle), I freely admit that it is designed and honed to be as fair and balanced as possible. Having a single Pokémon that completely shifts the way the game is played as you are admitting is tantamount to destroying any semblence of fairness or strategy. Whether either player carries Mega-Gengar would suddenly dictate what game you're playing, and what is viable, making the entire match a system of pot luck. As soon as people start running Never Used or Under Used Pokémon just to counter Mega-Gengar, players without them will start showing them just
WHY those Pokémon are in the lower tiers.
And this is assuming that those NUs or UUs actually can stop Mega-Gengar, which you have not yet proven or even strongly argued for.
What if you run Taunt on the Pokemon that MGengar is there to snipe? Of course, this only works for Pokemon that don't normally run Taunt as part of their set but still learn Taunt, and even then they will be forced to use a moveslot that might be taken up just to deal with MGengar. Of course, this could simply cause players to devise strategies through which Taunt is useful on that set, or a similar one, to benefit them outside of dealing with MGengar.
What if you scout/phaze MGengar as I suggested? You are then forced into a prediction war with your opponent, where you have to predict if he'll predict you switching to the Pokemon he needs MGengar to take out. It's all about mindgames; for example, you could lead your opponent on by playing into their hand just long enough for them to switch in the thing that needs MGengar's protection. They'll likely predict you switching to the counter, as you've been making fairly obvious plays thus far, and switch in MGengar, to which you switch in your counter-pick on the same turn.
Scouting and phazing him hurts you long run. You still can't stop him. He is too powerful, and too carefully crafted to take out his target. Either you never send your target out, in which Mega Gengar wins without being played, or you predict perfectly and double switch, in which case you're right back where you started, gaining you nothing. Or you fail to predict, and lose. Prediction or no, Mega Gengar against its target equals a dead target. All you've done is removed the one turn grace period for switching out, which Mega Gengar is not going to mind at all.
What I don't understand is why we aren't talking about Protect's role in all of this.
For MGengar to get off a Perish Trap it needs to 1) use Perish Song 2) Protect 3) Protect a second time in a row 4) Switch out to a "safe" pokemon
If MGengar is doing all 4 of these actions and you cannot cause sufficient damage to 1) kill gengar on the turn he Songs 2) kill gengar at the point there is a 50% chance you get a second attack on him 3) use a move on the pokemon he switches to that makes setting up to sweep 4) In the case of spamming sub instead of spamming protect the very fact you could have taunted him to prevent sub even if he were faster than you on the turn he songs (your opponent has to make a perfect prediction that you will either A) taunt him or B) attack him and either perish song or taunt that turn)... et cetera
If MGengar has Sub, Taunt, Protect, Perish Song he must correctly taunt to block your taunt on turn one, then song on turn two - but you're forced to attack him now anyway so he does damage this turn. Or, in the case of perish song on turn one and you taunt him, he can no longer protect/sub/taunt and has to switch out or take struggle damage on top of the damage you will cause him next turn... or you attack him when he perish songs anyway and receives that said damage... And really, if you have uturn/volt switch he can't stop you from switching out the turn he songs (and this forces him to switch out in 2 turns)... And really, if you have roar/whirlwind he also can't stop that, since protect no longer makes you immune... If you outspeed MGengar (like a Ninjask or something), you can also baton pass to a counter before he songs (or hell, after he songs, doesn't really make a difference).
There are numerous potential counter plays and your opponent needs to make perfect prediction in order to avoid them all.
Really, if you analyze the actual set of circumstances that have to occur for a Perish Trap to work without the MGengar/his team suffering a debilitating amount of damage that negates the loss of your pokemon... you will come to the conclusion this discussion is overblown and full of theory; theory that can only be properly debunked at this point with a suspect test.
If you analyze the
actual set of circumstances required for Mega-Gengar to
run a Perish Trap set, I think you'll find that most of them are facing Pokémon which won't be able to kill him before his turn is up, protection or no. It is meant for bulky walls that his attacks can't wear down. If you're being walled by a defensive Pokémon, how many of them run enough powerful attacks to KO Gengar, even if they predict the Perish Song perfectly? Blissey can't even touch Mega-Gengar.
