Empty's Melee Tier List as of April 2017
S Tier - Top Tier (Can be solo-mained to win any tournament on earth)
Fox - Obvious. Does not need justification.
Marth - Has been performing better than Falco in the current meta, with less limitations.
Falco - Still an excellent character, but struggling to perform currently.
Puff - Unreal matchup spread, high-risk, high-reward. Not as well represented, but there's more coming up.
Sheik - Can still do it, there's just a lack of reps at peak level. Plup's getting there, but reaction tech chasing is the future.
A Tier - High Tier (Can win any tournament in the right hands, but less easily or with counter picks)
Peach - Armada has optimized this character to an unreal degree. Why he isn't being outright copied is beyond me.
Falcon - On the hard come up. Has the tools, but is limited by his weaknesses. People are working around it.
ICs - Wobblefishing is becoming less viable, but Dizz isn't on the upswing because he's bad at melee.
Samus - Plenty of representation. Watch this space, I wouldn't be surprised to see her beat out the ICs.
Pikachu - The "bad Fox" narrative needs to go, it's scaring potential new players away. Axe isn't the end-all-be-all.
B Tier - Mid Tier (Can win any regional tournament or smaller major, or place top 8 at any super major, but has limitations)
Luigi - Imagine Plup's skill at movement, spacing, and fundamentals. Now, add in Luigikid or Abate's character knowledge/punish.
Yoshi - aMSa isn't going anywhere, in fact, he's stronger than ever in Japan. New Yoshis keep cropping up.
Dr. Mario - Even though he's dead in this meta, he's an underrated character that is another Shroomed away from being back.
C Tier - Low-Mid Tier (Potential is there to perhaps place reasonably at a major or get Top 100 wins, but still undeveloped.)
Ganondorf - I puzzle with placing Ganon here, but he's still somewhat of an untapped character. Almost B tier.
Mario - Limited by his inability to kill and inferiority to Doc. If Scorp was a separate person from Mang0, he'd be B tier.
Young Link - Marginally better than Link and with solid matchups against other lakers, but lacking in results.
Link - A few good wins in 2016 justifies him above DK. Squarely Low-mid tier.
DK - Has a good punish game, has a number of unique traits, and has bad neutral.
D Tier - Low Tier (Can attain decent results on a local to regional scale, but will not make Top 100 at this time.)
Mewtwo - Zoma and Leffen gave Mewtwo a decent 2016, and I take results fairly strongly into account.
Mr. Game and Watch - Depressing, how close he is to a good character. Still, players like Qerb and Kuya do alright.
Ness - My boy is by no means good, but isn't bottom 4. He desperately needs optimization, YYG and Movement are nutty.
Roy - Poor Roy is another character with a few positives but some disgusting negatives. Good in concept, no results.
Zelda - 2 godly kill moves, a decent recovery, and basically nothing else. A good ICs matchup keeps her out of E Tier.
E Tier - Bottom Tier (Borderline unplayably bad, but in some rare cases can perform.)
Kirby - Triple R makes me think this way, he has better results than the other 2 assholes in this tier. Okay tilts and edgeguarding.
Pichu - Designed to be the worst in the game, but missed the mark. Not by much though. His speed could someday bring him up.
Bowser - **** this character, incredible how bad this fat shart is. Sakurai pls
