I don't know about any of you guys, but I find the seismic toss variant of MegaKhan to be incredibly threatening.
I see a lot of Talk about the Power up Punch/ Return/ Earthquake/ Suckerpunch Variant, since that is by far the most common one... but guys, I cannot honestly say that Mega-khan is uber material. I mean seriously, give an NU pokemon a weaker version of swords dance (it might KO the pokemon on the first hit, it can be prevented with a ghost switch, iron barbs and rough skin are issues), 20 more base defenses in its defenses and 30 more base attack and suddenly it is being called better than arceus! Granted, it basically has soul dew hard built into it (though it has a few weaknesses)
It is still just a physically attacking set up sweeper. It is still countered by being burnt, by being paralysed (anyone who says that a megakhan with no speed is still a huge threat is just trying to get rid of a pokemon they don't use and don't want to play against because it is just as popular as rotom-W), and most ghosts still wall mega khan by default. Iron barbs still exist on ferrothorn, rocky helmet still exists, and if people are more inclined to use it because of megakhan then let them! It's about time that item got a bit more love, and it is extremely useful against most megas that are being seen.
The scariest and hardest khan to date I have been up against was one that caught me offguard. Seismic toss, knock off, wish, protect. Sounds really silly until parental bond starts hitting your pokemon for 60% unless you are a blissy.
Do I think that Megakhan is broken? No. For basically the same reason I don't think Alikazam with a life orb is. I think mega khan is an incredibly powerful wallbreaker, in both sets that I have seen it run. If your team generically prepares for physical threats (which mind you is MOST of the metagame) then you should not have an issue with mmegakhan. Saying that it can set up and sweep basically means you might as well ban Barbaracle because shell smash is broken on him.
If you get swept by megakhan, chances are you would have been gotten swept by Garchomp with SD as well (unless you were running focus sash, of course)
It would be nice to not have to see it every other game, but...
