The Beginning Of The End

When The Beginning Of The End enters the battlefield, destroy all non-planeswalkers in play.
Then, each player searches their library and/or graveyard for a planeswalker, reveals it, and puts
it onto the battlefield. If your opponents have
no planeswalkers in play, you win the game.
If you don't have Nicol Bolas, dragon god in your graveyard battlefield or exile,
you lose the game.

You are the only thing left"
