Darksteel Reactor + Eternity Vessel + The Ozolith + Does Machines

Darksteel Reactor

Eternity Vessel

The Ozolith

Does Machines

How it works

1. At the beginning of combat, Does Machines's last ability and The Ozolith trigger.
2. Resolve the Does Machines 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.
