Biovisionary + Echo Mage + Saheeli's Artistry

Biovisionary

Echo Mage

Saheeli's Artistry

How it works

1. Cast Saheeli's Artistry by paying its mana cost, targeting Biovisionary.
2. Holding priority, activate Echo Mage by tapping it, copying Saheeli's Artistry twice, with both copies targeting Biovisionary.
3. Resolve all Saheeli's Artistry 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 clever win condition relies on multiplying a single creature into an army in a single turn using Saheeli's Artistry to create multiple token copies of Biovisionary. To pull off this sorcery-speed trick, you need Echo Mage fully leveled up to level 4+ so that its tap ability can copy the initial spell twice, instantly producing the necessary quota of four identically named creatures. Once the stack resolves and your end step arrives, Biovisionary's own static condition checks your board state and instantly seals your victory.
