My vote of the ban of Gengarite: I vote to ban Gengarite.
Reasoning: One point in Special Attack from a Timid Mega-Gengar is higher than Modest Palkia/Kyogre's Special Attack. That is insane. Not only that, but the ability to remove almost any Pokemon in the Ubers meta is broken alone. Destiny Bond, Taunt, Perish Song, a plethora of coverage moves like for example Thunder, Sludge Wave, Focus Blast, Hp Fire, you have many options. Your team does not like Scizor? Hp Fire. Your team does not like Xerneas? Sludge Wave. Your Zekrom need Groudon gone so it can sweep? Destiny Bond. Your team hard walled by Blissey? Perish Song. It has you covered on many fronts of what it can remove for your team, and is an incredibly hard hitter with aforementioned Special Attack. The base 130 speed it has greatly backs it up to get the Destiny Bond off much easier than most can, and coupled with Taunt and the ability to trap with Shadow Tag, you will most definitely lose a Pokemon. Adding onto that, if the opponent is an excellent Gengar user, he will Mega+Destiny Bond to screw over a scarfer that you attempt to switch into that turn, and can heavily cripple you if you needed it for anything else. With that, it also causes 50/50's too. Will he Taunt the Groudon as your attempt to Stealth Rock or Roar? Or will he Destiny Bond predicting the EQ? You never know. That is why I believe this ban will be necessary.

It was fun to participate in this suspect test, the team that I used in the screenshots is what got me through. I saved a replay of why you need hazards or a good answer to Shedinja as a for fun thing:
