This loop transforms your library into an endless cycle of shadowy recycling by turning the top of your deck into a hidden hand. **Experimental Frenzy** grants you the vital permission to cast creatures straight from the top of your library, allowing **Priest of Gix** to re-enter the battlefield and generously refund three black mana upon arrival. Each time you sacrifice that same **Priest of Gix** to **Goblin Bombardment** to ping any target for damage, **Mortuary** immediately catches the falling creature and places it neatly back onto the top of your library. Because the black mana generated easily covers the casting cost while advancing your sinister agenda, you can repeat this sequence indefinitely to overwhelm your opponents.
