seems like Rad or Dark Blast combined with Time would do the trick.
My level 50 Dominators:
Madame Mindbender 50 Mind/Energy
Fly Agaric 50 Plant/Thorn
Nate Nitro 50 Fire/Psi
rad/time or dark/rad definitly one of those 2, would definitly suit your theme, change the colours and your set 
Im currently leaning more towards Rad/Time. Not really a fan of dark blast.
I would like to go with energy blast but its not great for Aoe =/
Indeed, Time seems a good fit for a secondary. Dual Pistols strikes me as closer to the theme of misfortune and luck than Energy or Rad, thematically.
Heres the build i came up with for the character.

Energy/Time or Energy/rad? hmm?
Which would better suit the theme of misfortune, luck, probability, reality altering, chaos?
P.S. I have been reading too much 'House of M, feature the Scarlet Witch
