Biovisionary

Mystic Reflection

How it works

1. Cast Myr Battlesphere by paying 7.
2. Myr Battlesphere enters the battlefield, triggering its ability.
3. Holding priority, cast Mystic Reflection by paying 1, causing the next creatures or planeswalkers to enter the battlefield this turn to enter as copies of Biovisionary.
4. Resolve the Myr Battlesphere trigger, creating four Biovisionary tokens.
5. At the beginning of your end step, each Biovisionary triggers.
6. Resolve the first Biovisionary trigger, causing you to win the game.
