Biovisionary + Echo Mage + Quantum Misalignment

Biovisionary

Echo Mage

Quantum Misalignment

How it works

1. Cast Quantum Misalignment by paying its mana cost, targeting Biovisionary.
2. Holding priority, activate Echo Mage by tapping it, copying Quantum Misalignment twice, with both copies targeting Biovisionary.
3. Resolve all Quantum Misalignment 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 trick relies on the incredible spell-duplication power of a fully leveled Echo Mage, which needs to reach level 4+ to copy an instant or sorcery twice. By casting Quantum Misalignment targeting your original Biovisionary and responding by tapping your leveled Echo Mage, you instantly flood the board with the necessary token copies. With the original and the new tokens all on the battlefield together, the delayed trigger from Biovisionary's own text does the rest of the work at the beginning of your end step, immediately sealing your victory.
