Sunspot is a great option, great damage and can be very useful, another option that's highly under-rated is emma frost, great damage when stacking prowess and can be very useful when in diamond form correct me if I'm wrong but she also has a synergy that allows her to be reverse control immune so yeh I'll be taking up my emma frost, she can be well annoying on defence too. So either emma frost or sunspot both great in my opinion.
