Expanding the Universe

Search your library for up to one basic land
card, reveal it, and put it onto the battlefield
tapped. Then shuffle your library.
If there are already a card named Expanding
the Universe in your graveyard, create Thanos,
a legendary 20/20 red and white legendary
creature token with "this creature can't attack
or block" and it has "{3}{r}{w}: sacrifice Thanos
and destroy all other permanents on the
battlefield"
