Banned via Warnings
*points at edited post that was added before this was added*Apparently, few people care enough about what SamuraiPanda says to read what he says thouroughly (and I've also pointed this out already).SamuraiPanda said this:
"One stage was actually voted counterpick/banned the first time, but I personally called for a revote because I discovered that it did the impossible... it counterpicked Metaknight. On that alone, the stage was voted in as counterpick."
So it's one of the following stages:
Brinstar
Corneria
Distant Planet
Frigate Orpheon
Green Hill Zone
Jungle Japes
Luigi's Mansion
Norfair
Pictochat
Pirate Ship
Pokémon Stadium 2
Rainbow Cruise
Yoshi's Island (Pipes)
My guess is Yoshi's Island (Pipes).
Oh, I see you edited your post while I was posting this.
I just noticed that Green Hil Zone is on that list. Doesn't that seem a little odd to anyone else? That might be it because I believe it used to be a counterpick/banned earlier this year.
Later on: It does make sense when I think about it a little. The spinning check marks do a good job of guarding against most of his attacks and they even out prioritize his tornado plus the stage gets rid of his gimping game. I'm testing it a little bit right now and I've also noticed that he slows down when running up and down the slopes in this stage and the spinning check points can kill him at as low as 65% (!). The breaking of the ground also forces him in the air which kills his ground speed thanks to his slow aerial movement. Hmm...
