This intricate engine uses Memnarch's first ability to turn Jan Jansen, Chaos Crafter into an artifact, allowing Jan Jansen to sacrifice Razorlash Transmogrant to its own activated ability. When Razorlash Transmogrant dies, Dross Scorpion triggers to untap Jan Jansen, while the sacrificed creature generates two Treasure tokens. Those Treasures provide the mana needed to replay Razorlash Transmogrant right back from the graveyard, looping the entire process to farm infinite sacrifices, leaves-the-battlefield, and death triggers.
