Yarus, Roar of the Old Gods + Master of the Veil + Viscera Seer

Yarus, Roar of the Old Gods

Master of the Veil

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Master of the Veil.
2. When Master of the Veil dies, Yarus' second ability triggers, returning Master of the Veil from your graveyard to the battlefield face down, then turning it face up.
3. Master of the Veil triggers, turning itself face down.
4. Resolve the Viscera Seer ability, causing you to scry 1.
5. Repeat.

This clever loop turns the cycle of life and death into a perpetual motion machine by leveraging the overlapping triggers of your board state. When you sacrifice Master of the Veil to Viscera Seer, Yarus, Roar of the Old Gods steps in to resurrect it face down and immediately flip it face up, triggering its own ability to turn itself back face down so the cycle can begin anew. Because Yarus grants your creatures haste and Master of the Veil's morph cost isn't even needed here, this self-sustaining loop endlessly repeats to let you scry through your entire deck while generating infinite sacrifices.
