Darksteel Reactor + Eternity Vessel + The Blackstaff of Waterdeep + The Ozolith

Darksteel Reactor

Eternity Vessel

The Blackstaff of Waterdeep

The Ozolith

How it works

1. Use The Blackstaff of Waterdeep 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.
