Biovisionary + Echo Mage + Ember Island Production

Biovisionary

Echo Mage

Ember Island Production

How it works

1. Cast Ember Island Production by paying its mana cost, targeting Biovisionary.
2. Holding priority, activate Echo Mage by tapping it, copying Ember Island Production twice, with both copies targeting Biovisionary.
3. Resolve all Ember Island Production spells, creating three token copies of Biovisionary.
4. At the beginning of your end step, each Biovisionary triggers. Resolve the first trigger, causing you to win the game.

This brilliant illusionist's trick relies on quickly multiplying a single threat into an overwhelming quorum, setting up Biovisionary's alternate win condition all in a single turn. By casting Ember Island Production to clone your original Biovisionary, you create the foundation for the replication. Meanwhile, Echo Mage at level 4+ provides the crucial multi-copy effect to instantly duplicate that spell twice on the stack. The resulting three fresh tokens join the original on the battlefield, immediately satisfying the four-creature requirement and securing your victory right at the beginning of the end step.
