Shilgengar, Sire of Famine + Ovalchase Daredevil + Bone Miser + Prognostic Sphinx

Shilgengar, Sire of Famine

Ovalchase Daredevil

Bone Miser

Prognostic Sphinx

How it works

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

This loop sets up an incredible engine of self-discard and recycling, powered by the synergy between Prognostic Sphinx and Ovalchase Daredevil. By feeding the Daredevil to Prognostic Sphinx’s activation cost, you send the artifact creature right back to your graveyard, which in turn triggers Bone Miser to continuously churn out 2/2 Zombie tokens whenever you discard it. Shilgengar, Sire of Famine acts as the ultimate catalyst for the engine, letting you sacrifice those generated Zombies to fuel its first ability and create a steady stream of Blood tokens. Every time a Blood token hits the battlefield, Ovalchase Daredevil's reflexive trigger conveniently bounces it right back to your hand, allowing you to feed the exact same card back into Prognostic Sphinx for infinite repetitions.
