Whenever a creature you control enters, put a devotion counter on Monument of the Masses. At the beginning of your upkeep, if Monument of the Masses has thirty-five or more devotion counters on it, you win the game.

If Monument of the Masses is destroyed in response to the trigger, but no devotion counters are removed from it, the player still wins the game. Better deal with it before then.
