To pull off this vintage-legal victory, you first rely on Vedalken Orrery to grant your spells flash, allowing you to bypass sorcery timing restrictions and lay your groundwork right on the end step before your turn. You then cast Channel, which gives you the raw, instant-speed power to repeatedly tap into your own life total and convert it directly into colorless mana. By activating Channel over and over until you reach precisely 1 life, you safely skirt the edge of elimination while setting the exact table state you need. Once your upkeep arrives, Near-Death Experience triggers because of that exact 1-life threshold you engineered, instantly sealing your victory before your opponents have a chance to react.
