This elegant loop turns a simple exchange of creatures into an endless execution engine, anchored by Blasting Station to turn every cycle into a point of direct damage. You kick off the loop by casting Faceless Butcher, whose entry triggers its exile effect while Blasting Station's static untap ability arms itself for the carnage ahead. By cycling Faceless Butcher in and out of the graveyard, you continuously trigger Metamorphosis Fanatic to resurrect the Butcher the moment it hits the bin, fueling the sacrifice outlet indefinitely.
