To Me, My X Men!

Reveal X cards from the top of your library. Put
any number of Mutant cards revealed this way
into your hand, and the rest on the bottom of
your library in any order. If you control one or
more legendary Mutants, also put one of the
Mutants revealed this way onto the battlefield.
"You've proven you can think and act for
yourselves!! Your training period is over!
Congratulations, my X-Men!"
