3. Resolve each Repeated Reverberation, causing you to copy the next instant or sorcery spell you cast six times.
4. Cast Phyresis Outbreak by paying 2.
5. Each Repeated Reverberation triggers, copying Phyresis Outbreak a total of nine times due to Twinning Staff.
6. Resolve each Phyresis Outbreak, causing each opponent to get ten poison counters.
7. Each opponent loses the game due to having ten or more poison counters.
