This came in Jubilee's pack, but it feels much more like a Magneto card. It works with Children of the Atom, and it's arguably better than Magneto's leadership cards. Plus it's another card that works better in multiplayer. For 3-cost, you get to:
thwart or attack with two allies,
reuse their "when revealed" effects,
completely heal them,
thwart or attack with those allies again.
