So if I personally play really good Jigglypuffs I should take that into account as much as tournament results when making a tier list?So, in conclusion, there's really not one amazing thing to base a tier list off of. Tourney results, matchups, potential, and even personal experience all have a near equal role in determining a tier list. It just so happens that of these things, tourney results are the most concrete and factual, yet they still are quite flawed.
