Demonlord Belzenlok + Selective Memory + Jace, Wielder of Mysteries

Demonlord Belzenlok

Selective Memory

Jace, Wielder of Mysteries

How it works

1. Cast Selective Memory by paying 3, exiling all nonland cards in your library.
2. Cast Demonlord Belzenlok by paying 4.
3. When Demonlord Belzenlok enters the battlefield, it triggers, exiling the remainder of your library.
4. Activate Jace's first loyalty ability by putting a loyalty counter on it, causing you to mill two cards and win the game due to drawing from an empty library.
