This clever loop harnesses the board-clearing power of Necromantic Selection while setting up a self-sustaining recursive engine. By timing the cast of Dualcaster Mage right after your sorcery, its entry trigger targets the original spell on the stack to create an endless succession of copies. Each resolved copy sweeps the board and immediately brings Dualcaster Mage back from the graveyard as a Zombie to copy the next one, generating infinite entries, exits, and death triggers.
