Biovisionary + Progenitor Mimic + Gogo, Master of Mimicry

Biovisionary

Progenitor Mimic

Gogo, Master of Mimicry

How it works

1. At the beginning of your upkeep, Progenitor Mimic triggers.
2. Holding priority, activate Gogo by paying 2 and tapping it, copying Progenitor Mimic's trigger.
3. Resolve both triggers, creating two token copies of Biovisionary.
4. At the beginning of your end step, each Biovisionary triggers.
5. Resolve the first trigger, causing you to win the game.

This clever loop hinges on multiplying the upkeep trigger of Progenitor Mimic, which enters the battlefield as a copy of Biovisionary. By using Gogo, Master of Mimicry to copy that upkeep trigger, you bypass the usual restriction of only making one token at a time and rapidly flood the board. Once you cross the threshold of controlling four or more creatures named Biovisionary, their static win condition triggers at the beginning of the end step to instantly seal your victory.
