Hermit Druid + Mana Severance + Jace, Wielder of Mysteries

Hermit Druid

Mana Severance

Jace, Wielder of Mysteries

How it works

1. Cast Mana Severance by paying 1, searching for all lands in your library, exiling them and shuffling your library.
2. Activate Hermit Druid by paying and tapping it, causing you to mill your entire library.
3. Activate Jace's first loyalty ability by putting a loyalty counter on it, causing target player to mill two cards and you to win the game due to drawing from an empty library.
