I don't honestly listen to tier lists, as they're all made by one person, who has their own personal preferences, and biases. I prefer to have my own opinions, not copy someone else's, or what's popular opinion, nor depending on tier lists to validate my opinions.
(Not accusing you of that, but some gamers do that.)
I honestly don't really have a bottom tier list. I even enjoy characters I'm bad at sometimes. SSB is just fun for me.
