I was the one guy who voted Olimar as high tier...whoops!
Anyway, there's been a bit of talk going around about what would happen if we were to ban Lylat and Duck Hunt, the two most gimmicky stages that are still legal (one is even a starter!). That would leave us with five legal stages, four of them being starters, but as you might know there needs to be an odd amount of starters for the stage striking process to work. The question now would be which starter to turn into a counterpick, and in my opinion, it would be
Town and City. The reason is that it would be the most gimmicky starter stage left, with small blast zones and platforms that are in lots of different locations, move slightly, and can carry you off the stage. And honestly, I could actually see a meta with Final Destination, Battlefield, and Smashville as starters with Dreamland and Town and City as counterpicks happening in the future. It would be the most balanced stage list, with the worst gimmicks being possible stretcher platform deaths and wind shenanigans, which aren't as bad as stage tilting and going through the stage (in Lylat) or obstacles in the sky, temporary fast-moving platforms, and extremely high platforms (in Duck Hunt).
