Astral Dragon + Biovisionary + Mirage Mirror

Astral Dragon

Biovisionary

Mirage Mirror

How it works

1. Cast Astral Dragon by paying 6.
2. When Astral Dragon enters the battlefield, it triggers, creating two token copies of Mirage Mirror that are 3/3 Dragons in addition to their other types.
3. Activate the three Mirage Mirrors by paying 6, causing each of them to become a copy of Biovisionary until end of turn.
4. At the beginning of your end step, Biovisionary and each Mirage Mirror trigger.
5. Resolve the first trigger, causing you to win the game.
