Challenge Games

Challenge Games enters the battlefield with 1
charge counter.
At the beginning of each player's untap step, that
player gains control of all Mob Horror creature
tokens on the battlefield. If there are no Mob
Horror creature tokens on the battlefield, that
player instead creates a number of 5/1 Mob
Horror creature tokens with haste equal to the
number of charge counters on Challenge Games,
then puts a charge counter on Challenge Games.
