Parallel Lives

How it works

1. Cast Astral Dragon by paying 6.
2. Astral Dragon enters the battlefield, triggering itself and Miirym.
3. Resolve the Astral Dragon trigger, creating four token copies of Parallel Lives that are 3/3 Dragons in addition to their other types.
4. Resolve the Miirym trigger, creating a total of 32 Astral Dragon tokens.
5. The Astral Dragon tokens enter the battlefield, creating an extremely large number of Parallel Lives tokens that are 3/3 Dragons in addition to their other types.
