2* Magneto + 2* Storm works great, mainly because Magneto's purple feeds Storm's devastating blue. Pair with Thor or Ares for red/yellow/green abilities.

2* Wolverine + Daken gives you full strength in all colors, and they can fill the board with strike tiles. If you can pair that with Falcon you regular attacks start looking like specials.

Once you start getting into 3*s, your options really open up, but if you're growing your roster organically (ie, not using HP to directly power them), your strategy will be dictated by whomever you get covers for first. Just go with whoever passes your best 2*s first and try to complement their colors.
