Shavah, Profane Saint

Flying, first strike, lifelink, deathtouch
Dreadful Prayer-Whenever this creature becomes
tapped, each player may put a permanent card
with mana value 3 or less from their graveyard
onto the battlefield tapped under their control
with a profane counter on it. (At the begining of
each player's upkeep, that player must sacrifice any
permanents with mana value less than the number of profane counters on it.)
