Darksteel Reactor + Eternity Vessel + Workshop Elders + The Ozolith

Darksteel Reactor

Eternity Vessel

Workshop Elders

The Ozolith

How it works

1. At the beginning of combat, Workshop Elders and The Ozolith trigger.
2. Resolve the Workshop Elders trigger, making Eternity Vessel a creature.
3. In response to the remaining trigger, cause Eternity Vessel to leave the battlefield.
4. The Ozolith triggers, putting a number of charge counters on itself equal to the charge counters that were on Eternity Vessel.
5. Resolve The Ozolith trigger from step 1, moving all counters from it onto Darksteel Reactor.
6. Darksteel Reactor triggers, causing you to win the game.
