Voice of Demons

Flash, Lifelink.
When Voice of Demons enters the battlefield, you may return 2 Angels to their owners hands. If you do, burn two lands you control and 2 you don't control.
I speak the word of the Kingdom of Fire. Heed me, for we are ready to cleanse this plane again. Maguma's breath will cleanse this plane of the weak, making way for the strong.
