Ostryy Zub, Master of the Moon

Werewolves you control have trample
{t}{r/g}{r/g}: You get an emblem with "If you control three or more werewolves, werewolves you control cannot flip unless you pay {1}."
When Ostryy Zub dies, return him to the battlefield at the end of turn with three tribe counters on him. Ostrry Zub cannot attack or block if he has a tribe counter on him. Remove one tribe counter when you cast a werewolf card.
