Darksteel Reactor + Eternity Vessel + The Ozolith + Bello, Bard of the Brambles

Darksteel Reactor

Eternity Vessel

The Ozolith

Bello, Bard of the Brambles

How it works

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