Biovisionary + Finale of Promise + Clone Legion

Biovisionary

Finale of Promise

Clone Legion

How it works

1. Cast Finale of Promise by paying 10, causing you to cast Clone Legion from your graveyard without paying its mana cost and copying it twice, with all spells targeting you.
2. Resolve all Clone Legions, creating three token copies of Biovisionary and every other creature you control.
3. At the beginning of your end step, each Biovisionary you control triggers.
4. Resolve the first trigger, causing you to win the game.

By pumping a massive amount of mana into Finale of Promise, you unlock its ability to replay and triple-copy spells from your graveyard. You target a Clone Legion with this flurry, turning a single original into three distinct copy spells targeting yourself. When those Clone Legions resolve, they multiply your existing board—including a lone Biovisionary—into four or more identical copies of every creature you control. This sudden swarm effortlessly satisfies the alternate-win condition printed right on Biovisionary, closing out the game at the start of your end step.
