For quite some time now, Pokkén players have been able to make presentable, organized tier lists through the use of a script made by kaloncpu57. In order to make a tier list, players would need to install the Tampermonkey/Greasemonkey browser extension, add kaloncpu57's script to the extension, then navigate to the Smash Apps Tier List Maker and change the game to Pokkén Tournament. While it was great that players could easily make tier lists, some people didn't like having to install an extension they were unfamiliar with in order to use the tier list maker. This is no longer an issue, as kaloncpu57 has released his own browser extension, eliminating the need for Tampermonkey or Greasemonkey!
Now, once you install kaloncpu57's browser extension, Pokkén Tournament will always be a game option when you navigate to the Tier List Maker app. You can find all of the necessary links below for making your own Pokkén Tournament tier list.
