Jubilee #28.
Mutant Mayhem
Reviews

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.
