When you are playing Medley Matches, you need to pick 5 different team members, one from each of these categories:
Heroes (Sonic, Tails, Mario, or Luigi)
Girls (Amy, Peach, Daisy, or Blaze)
Tricksters (Wario, Waluigi, Dr. Eggman, or Metal Sonic)
Wild Ones (Knuckles, Bowser, Donkey Kong, or Vector)
Challengers (Yoshi, Shadow, Bowser Jr, or SIlver)
Does it matter who I pick? Are certain characters better for certain events? Or is it a purely aesthetic choice?
