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.
