Harouki said: It's simple. Look at the colors and take a guess.
Homura = Darkness/Steel Mami = Electric Kyouko = Fire Sayaka = Ice/Water Madoka = Random group as per the Champion's shtick
The champion doesn't always have a random group. Gen 2 and 3 were type specific or at least had a theme (Dragon and Mineral/Water respectively). Considering Madoka's personality, Normal or random seem fitting.
Also, Dark and Steel is very appropriate for Homura. Dark attacks are cheap/pragmatic and Steel attacks are metal/machinery, i.e. the guns and explosives she uses.

They seem to be moving towards having a balanced team, if Gens 4 and 5 are anything to bite at.
