- Color identity
- B
- Mana
- {1}
Steps

- Due to Dauthi Voidwalker's replacement effect, the milled card is exiled instead of going to the graveyard, and that opponents repeats that process until their library is empty.
How to execute this combo
The "Helm of Obedience + Dauthi Voidwalker" combo takes 2 steps in order. Make sure you have the mana open and permanents listed in the prerequisites before you start — opponents can respond between steps.
The end result: Exile target opponent's library.
Practice the line offline: lay out the cards, walk through each step, and note where you can lose the combo (summoning sickness, lack of priority, removal on a key permanent). In game, announce each step clearly; in casual play you can offer to shortcut after demonstrating the loop.
The best window is a turn when opponents are tapped out or after they commit a spell — hold protection (a counter, Vexing Shusher) if the combo wins on the spot.
