Whenever you begin playing League of Legends,
each player creates a Nexus planeswalker token.

don't control.
Whenever a Nexus leaves the battlefield, that
creature's controller loses 4 life and discards 2
cards, each of their opponents gain 4 life and
draw 2 cards. Then end this game and exile all
other Nexus tokens.
