Which five-star crystal should I open?

DoctorofEvil

Currently my only R3 or higher worthy 5 stars are AA (duped)Hyperion, SL (Duped), KM, GP, Quake, Red Hulk, Wasp, Hela, Ulton, and WS. Also have a duped She-Hulk and Spidergwen that might be worth a good rank if the buffs remain as they are in the beta. Looking at the crystals - I lack any good power control champs so I am leaning toward the Genesis crystal, but the evolution crystal seems to be the best blend of talent. What do you think? her his a summary of the crystals.

Chaos: Medusa, Beast, Iron Man, RR, WS, Taskmaster, CA, MODOK, Thor (JF), Dorm
Nightmare: Omega Red, Guillotine, SM (Symb), MM KK, Red Sk, Ultron, BP, XB, RH, Rhino

Whatever crystal promises the most new champions or useful awakenings. No point opening a crystal with only 2-3 of these possibilities if another has 7 or 8.
