Here are 7 characters with steeper learning curvesI think that theory of the metagame revolving around Marth is BS tbh. Marth has possibly the steepest learning curve in the game
Link (Lots of AT's Good Luck)
Yoshi (Awesome AT's Like Dragonic Reverse)
Iceclimbers (Chaingrab anybody)
Pikachu (can you QAC everywhere?)
Toon Link (See Link)
Pokemon Trainer (Handel all 3 perfectly. Good Luck)
Diddy Kong (Learning him will Drive you Bannanas)
Even Sonic and Pit can give your claim a run for your money.
I hope I got props for the Diddy Kong pun.
Matchups don't have to be at the absolute highest level of play. Just higher levels of play.
After meta, Marth will only have 2 argueable bad matchups, Snake and ROB. Thats the least amount of any character once meta is gone.
As a Link main who put his life into spacing and zoning, marths metagame came easy to me. (Look at my sig)
I can tell you that marth does not even come close to having a steepest learning curve. His learning curve is only above average at best....
Marth will be the character to play but at least you can counter him....unlike metaknight.
