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.

I like this (along with children of the atom) on mutants with useful signature allies such as x-23's honey badger. This allows x-23 to reset honey badger's hp, get some dmg/thwart in and get another ready. Bounce the cyclops ally and you can stack a bit of dmg.

Cyclops, phoenix, rogue, angel, psylocke and wolverine's allies can leverage this well too.

Of course, this is still useable on non-mutant heroes that pack alot of x-force/x-men allies.
