The Ring Goes South

The Ring tempts you. Then reveal cards from the
top of your library until you reveal X land cards,
where X is the number of legendary creatures you
control. Put those land cards onto the battlefield
tapped and the rest on the bottom of your library
in a random order.
End? No, the journey doesn't end here. Death is
just another path, one that we all must take.
The grey rain-curtain of this world rolls back,
and all turns to silver glass, and then you see it.
