Killer Frost/Prime is unlikely, as she was repeated after Darkseid/Apokolips. She'd also be a relative waste of a repeat/challenge space, as she's a guaranteed pull in the Ice Breaker Booster which will soon debut. Hawkgirl/Regime could be upcoming if we're lucky, whatwith the two Arkham characters chronologically occuring after Killer Frost having been recently available in the Arkham pack.
