Miirym, Sentinel Wyrm + Astral Dragon + Anointed Procession

Miirym, Sentinel Wyrm

Astral Dragon

Anointed Procession

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 Anointed Procession 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 Anointed Procession tokens that are 3/3 Dragons in addition to their other types.

This engine relies on a brilliant multiplicative cascade fueled by Miirym, Sentinel Wyrm and Astral Dragon. When Astral Dragon enters the battlefield, its triggered ability targets Anointed Procession, which doubles token creation, while Miirym triggers to make a nonlegendary copy of the entering Dragon. Thanks to Anointed Procession sitting on the battlefield, those replacement effects multiply the copies exponentially into an overwhelming swarm of 32 Astral Dragon tokens, which in turn trigger more copies of Anointed Procession to flood the board with nearly infinite creatures and entry triggers.
