I would actually prefer to add FoD to the couterpick list instead of stadium, it's a little small and subtly more dynamic imo. I'm with you on that.
I just think Green Green's blocks are very obtrusive. the only way to move is to jump, and characters whose movement or comboing relies on being on the ground like luigi, mario, or sheik are hindered. I understand that that is the purpose of the counterpick, but I think it's too much. this stage is just too tricky. there's also bombs and apples.
for jungle japes, the ceiling is just sooo high and the ground too low. hogging the edge is dangerous in itself, and nobody can recover low without being at risk of the stage itself.
pokefloats seems like a more obtrusive version of rainbow cruise. personally I just don't like it.
all of the CP stages kind of make your one ban pretty moot if you ask me. then if we get two bans, the whole system is just confusing.
I kinda want another name for the tourney tbh
