This is something I've noticed too. Iceman's consistently ranked #1, but what I see most in PVP is Jeanbusters, not Icebusters. The character's super good on his own - does he just not have a viable partner?
Maybe the issue is that if you use him with a red nuker, his purple works against you, and the other good options involve too much color overlap. Cyke and HB can generate reds without matching reds, but in both cases you're losing their blues.

thor for his yellow -> accelerates bobbys green
hulkbuster for black and red ->dead person
iceman green, pink, blue
only problem i see with this team is its speed. that team hits hard and prolly good on defence, but its slow. really slow
