This ingenious win-the-game engine relies on animating Eternity Vessel into a creature with Rise and Shine so that its massive pile of life-total-derived charge counters can be harvested when it leaves the battlefield. Those counters are safely caught by The Ozolith, which preserves them until your combat step and safely transfers them onto Darksteel Reactor. Once Darksteel Reactor receives that sudden deluge of counters, its innate win condition immediately satisfies, bypassing the slow, turn-by-turn grind normally required to reach twenty counters.
