Great quiz, but I would change a few things. First of all, Pokemon Trainer should be accepted for Charizard. Secondly, Squirtle, Shulk, and Yoshi should all be added (even though for Shulk and Yoshi the recovery utility is essentially useless). Lastly, I would make mention of the fact that technically, every side B CAN be useful for preventing edge guards, and by extension helpful in recovery (Wii Fit's is actually VERY useful as an off stage get off me tool and stall in the air).
