The SBR should add a bottom tier to this tier list, as usual. Mario, Samus, Lucas and Ness are not bottom for sure (they're not at the same level as Falcon by example), but maybe low.
From this tier list (and not from my personnal thoughts), the tiers may look like this :
Low
27. Lucas
28. Ness
29. Mario
30. Pokémon Trainer
31. Samus
Bottom
32. Yoshi
33. Sonic
34. Jigglypuff
35. Ganondorf
36. Link
37. Captain Falcon
There are not so many characters in low / bottom tier (11 characters, 12 in Melee), only because there are a lot more good characters in Top / High Tiers. That doesn't mean we should forget this "bottom" tier.
