The Rite of God Yawgmoth

The Rite of God Yawgmoth enters the battlefield with two phyrexian counters on it. Remove a phyrexian counter from all permanents you control at the beginning of your upkeep. Then, if you control no permanents with phyrexian counters on them, destroy all non-black creatures.
Whenever you remove a phyrexian counter from a permanent, you lose 1 life and draw a card.
