Biovisionary + Repeated Reverberation + Quasiduplicate

Biovisionary

Repeated Reverberation

Quasiduplicate

How it works

1. Cast Repeated Reverberation by paying 2, copying the next instant or sorcery spell you cast twice.
2. Cast Quasiduplicate by paying 1, targeting Biovisionary.
3. Repeated Reverberation triggers, copying Quasiduplicate twice, with both copies targeting Biovisionary.
4. Resolve all Quasiduplicates, creating three token copies of Biovisionary.
5. At the beginning of your end step, each Biovisionary triggers.
6. Resolve the first trigger, causing you to win the game.
