How it works
Prerequisites
- "Dragon" chosen with Molten Echoes.
Steps
- 1Cast Worldgorger Dragon, triggering Molten Echoes and Worldgorger Dragon's ETBs; stack the triggers to resolve in that order.
- 2Resolve Molten Echoes' trigger, creating a token copy of Worldgorger Dragon and triggering its ETB.
- 3Float as much mana as you want in response to the token's ETB trigger.
- 4The token's effect resolves, exiling everything else you control, including the original Worldgorger Dragon.
- 5Resolve the original Worldgorger Dragon's LTB with no effect, then resolve the ETB trigger of the original Worldgorger Dragon, exiling the token copy.
- 6Resolve token Worldgorger Dragon's LTB trigger, returning everything it exiled to the battlefield under your control.
- 7Name Dragons as Molten Echoes enters the battlefield.
- 8Repeat the loop from the top for infinite mana.
- 9Repeat this process until you have infinite mana.
- 10The loop can broken by naming a different creature type as Molten Echoes enters the battlefield.
