NOTE - Tiers may be subject to change, depending on general consensus on what character is good or bad. Also, these are not forced onto the player; meaning anyone can play the game how ever they want.
This is the official tier list for Mushroom Kingdom Showdown 0.9, created by the MKS Backroom. The two members of the backroom are NilZAR and KnucklesSilver7.
The tiers are created with the mindset of "not every character is bad, but some characters are better than others". These tiers are created based on how characters play without the use of showdown attacks, and on stages with closed blast zones (ex: Mushroom Plains).
Due to the backroom members becoming inactive on the wiki, a official 1.0 tier list is unlikely.
