Pang Liao, the Indomitable

While you control at least three other exemplar creatures, if this creature isn't exemplar, it becomes exemplar. (To make a creature exemplar, double its base power and toughness. Exemplar creatures have protection from enchantments.)
At the beginning of your upkeep, put a -1/-1 counter on each creature that isn't named Pang Liao, the Indomitable.
