Krabs' One Millionth Dollar

(You may cast a legendary sorcery only if you
control a legendary creature or planeswalker.)
Look at the top X cards of your library.
You may put any number of land and/or
legendary permanent cards with mana
value X or less from among them onto the
battlefield. Put the rest into your graveyard.

“Congratulations, sir! You have just given me
my one-millionth dollar!"
