Biovisionary + Mnemonic Deluge + Repudiate // Replicate

Biovisionary

Mnemonic Deluge

Repudiate // Replicate

How it works

1. Cast Mnemonic Deluge by paying 6, exiling Repudiate // Replicate and casting three copies of Replicate without paying their mana costs.
2. Resolve the three Replicate copies, creating three token copies of Biovisionary.
3. At the beginning of your end step, each Biovisionary you control triggers.
4. Resolve the first trigger, causing you to win the game.

This astonishing win relies entirely on turning a single creature into a full-fledged victory condition through clever spellcopying. By deploying your initial Biovisionary and then casting Mnemonic Deluge targeting the versatile Repudiate // Replicate already resting in your graveyard, you instantly generate three separate copies of the Replicate half. Because Mnemonic Deluge lets you cast those copies without paying their mana costs, you rapidly flood the battlefield with three brand-new token copies of Biovisionary. With four total identical creatures now under your control, the original Biovisionary's static check triggers at the beginning of your end step, immediately closing out the game in your favor before your opponents can react.
