I've got beef with that tier list if Shyguy, the only dice with a guaranteed number on 5 out of 6 spots, and an above average roll at that as a 4, is somehow worse then peach, who has way more variance. Tier lists are always subjective, so I'm not gonna saying it's bad, I just have different preferences.
Seriously though, since you always have access to a normal dice either way, if you go friendless, shyguy is amazing!
