My list
going to say what I think
Neutrals:
Battlefield Probably Most neutral stage, definite yes
Final Destination: same
Smashville: same
Yoshi's Island: same
Delfino: the stage moves but no specific character ha s a weakness, all the of the walls or the walk off areas can be easily avoided or people can just camp until its a better area
Lylat Cruise: of course the area curves, projectile characters are slightly weaker, but no real disadvantage to most characters
Counterpicks
Castle Siege: certain characters do overly well here (see D3), middle section is the only portion that is truly broken, if it stayed on the middle section the longest, i would say banned or counterpick
Halberd: Ceiling is too low, Snake's up tilt is broken here, Metaknight is also really good here, otherwise, no real problem, hazards are easily avoidable
Pokémon Stadium 1: Walls + Windmill, either this or banned
Brinstar: a good DK stage....wut, fire isn't as powerful as on Norfair, fire assists recoveries, no major problems
Hanenbow: Is there really a problem with this stage or does everyone just hate it THAT much
Distant Planet: Side is campy, water is a problem, because the stage is curved grabs aren't broken
Frigate Orpheon: anti snake stage, whats not to like, platform shifts
Jungle Japes: Stage is too high, Klap traps come every 10 seconds, water assists some recoveries, anti-snake (kind of)
Norfair: Platforms are odd, flames can be avoided, kinda campy, but not horrible
Pirate Ship: Either this or banned, cannon is powerful, water assists recoveries, would ban it if the portion lasts a bit too long
Rainbow Cruise: Anti-chaingrab, either this or banned
Banned:
Pictochat: Movements are random, certain portions effect too many characters, missile does 25 damage, Spears do 20 and kill very easily, Spikes do 30
Luigi's Mansion: Cave of life, Campiest stage in the world, cave of life, certain characters are overpowered
Wario-ware: Where was this stage, you never included it, minigames are fun but cause too much turmoil
Pokémon Stadium 2: the effects are broken, electricity causes SD's, ice causes odd movements, other one has walls, main platform is fine
Corneria: sorry ness user's, campy, lasers intercept stuff, wall allows infinite
Yoshi's Island (Pipes): toon link is too good, walk off
Green Greens: either counterpick or banned, too low a ceiling, walls are campy, Blast glitch
Mario Circuit: Walk off, cars
Onett: Walls, cars
Port Town Aero Dive: cars kill you at 40, NO
Skyworld: Ganon's forward b is too good, platforms are broken, literally
75m: Too large, broken areas, walk of's, fire
Big Blue: Cars are broken, stage moves too much
Bridge of Eldin: Walk off, too large, campy, D3 chain grab, falco lasers
Flat Zone 2: Too Small, broken projectiles, probably the most broken stage
Hyrule Temple: Cave of Life, too large, campy
Mario Bros: Walls, cave of life, overpowered projectiles
Mushroomy Kingdom I: moving, stage camping, back throws
Mushroomy Kingdom II, cave of life (technically), walls, camping, back throw's
New Pork City: WAY....TOO....LARGE
Rumble Falls: Moves badly, moves too quickly, Green things kill people at 40
Shadow Moses: If walls aren't broken, infinites, if walls are broken walk off
Spear Pillar: bottom portion is cave of life, pokemon effect stage too much
The Summit: Gravity, bottom portion is either cave of life or overpowered.
Green Hill Zone: Too Campy,check points have too high priority, walls break
