Shilgengar, Sire of Famine + Ovalchase Daredevil + Skeleton Crew + Prognostic Sphinx

Shilgengar, Sire of Famine

Ovalchase Daredevil

Skeleton Crew

Prognostic Sphinx

How it works

1. Activate Prognostic Sphinx by discarding Ovalchase Daredevil.
2. Activate Shilgengar's first ability by sacrificing another creature, creating a Blood token.
3. When the Blood enters the battlefield, Ovalchase Daredevil triggers, returning Ovalchase Daredevil from your graveyard to your hand.
4. Skeleton Crew triggers, creating a 2/2 Skeleton Pirate creature token.
5. Repeat.

This intricate loop relies on Prognostic Sphinx's ability to pitch cards to the graveyard—specifically feeding Ovalchase Daredevil directly from your hand. Whenever Shilgengar, Sire of Famine sacrifices a creature to generate a Blood token, that newly arriving artifact triggers Ovalchase Daredevil to return to your hand, fueling the Sphinx's discard cost all over again. Meanwhile, Skeleton Crew watches quietly from the battlefield, capitalizing on Ovalchase Daredevil leaving your graveyard to churn out an endless horde of Skeleton Pirate tokens.
