Biovisionary + Echo Mage + Sublime Epiphany

Biovisionary

Echo Mage

Sublime Epiphany

How it works

1. Cast Sublime Epiphany by paying its mana cost, targeting Biovisionary.
2. Holding priority, activate Echo Mage by tapping it, copying Sublime Epiphany twice, with both copies targeting Biovisionary.
3. Resolve all Sublime Epiphany 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 loop turns a single spell into a game-winning board state by taking full advantage of the stack and the token-copying power of Sublime Epiphany. Once you cast Sublime Epiphany to clone Biovisionary, Echo Mage's fully leveled-up ability steps in to multiply that spell into three total instances. When these resolve, they instantly field the required quartet of Biovisionary creatures, setting up your impending victory. All that remains is to coast into your end step, where the accumulated Biovisionary triggers successfully check for four copies and instantly win you the game.
