Biovisionary + Echo Mage + Relm's Sketching

Biovisionary

Echo Mage

Relm's Sketching

How it works

1. Cast Relm's Sketching by paying its mana cost, targeting Biovisionary.
2. Holding priority, activate Echo Mage by tapping it, copying Relm's Sketching twice, with both copies targeting Biovisionary.
3. Resolve all Relm's Sketching 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.
