I think what would be a lot more useful than a list of all teams, or even just top teams, would just be the original list being debated (single chars rated), and then a quick list for each chars of their best 'teammate chars'. This mostly seems useful to me for those interested in making a team. Say I want to play Pikachu in teams, but don't know what team might work for him. Further say I have three friends (potential teammates) who play Fox, Peach, and Jiggs. Turns out Fox + Pikachu is awesome, Peach + Pikachu is alright, and Jiggs + Pikachu is kinda bad. Now I know and can team with Fox friend! Thanks tierlist!
I realize for much of low tier it may turn into "add Fox or Sheik to your team for best results", but there's still some notable cohesion between certain low tiers and other chars that is unique to that low tier (and every char for that matter).
