Darksteel Reactor + Eternity Vessel + The Ozolith + Karn, the Great Creator

Darksteel Reactor

Eternity Vessel

The Ozolith

Karn, the Great Creator

How it works

1. Use Karn, the Great Creator to make Eternity Vessel a creature.
2. Cause Eternity Vessel to leave the battlefield.
3. The Ozolith triggers, putting a number of charge counters on itself equal to the charge counters that were on Eternity Vessel.
4. At the beginning of your combat phase, The Ozolith triggers, moving all counters from it onto Darksteel Reactor.
5. Darksteel Reactor triggers, causing you to win the game.
