How it works

1. Activate Thunderclap Drake by paying 2 and sacrificing it.
2. Cast Replicate by paying its mana cost, targeting Biovisionary.
3. Thunderclap Drake triggers, copying Replicate at least twice, with all copies targeting Biovisionary.
4. Resolve all Replicate spells, creating at least three copies of Biovisionary.
5. At the beginning of your end step, each Biovisionary triggers, causing you to win the game.
