Sisters of the Atom

Ready for thwarts until there isn't any threat left. Then just use all of the readies for attack. Children of the Atom is there so she can make use of additional readies via Utopia. Lots of card draw and mostly cheap cards in the deck other than the allies. Allies will also have sustain via Mission Training.

edit: I'd swap Husk for Triage. Cheaper ally and you can heal X-23 after Children of the Atom is out. Alternatively, you could swap Husk for Under Surveillance when playing solo.
