Shilgengar, Sire of Famine + Ovalchase Daredevil + Bone Miser + Psychic Frog

Shilgengar, Sire of Famine

Ovalchase Daredevil

Bone Miser

Psychic Frog

How it works

1. Activate Psychic Frog by discarding Ovalchase Daredevil
2. Bone Miser's first ability triggers, creating a 2/2 Zombie creature token.
3. Resolve the Psychic Frog ability, putting a +1/+1 counter on it.
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 turns the simple act of discarding into an infinite engine, anchored by Psychic Frog as the discard outlet that pumps itself with +1/+1 counters while pitching your hand. Every time you discard Ovalchase Daredevil, Bone Miser capitalizes on the discard to produce a 2/2 Zombie creature token, which Shilgengar, Sire of Famine can immediately sacrifice to generate a Blood token. The brilliance of the loop lies in that Blood token's entry: it triggers Ovalchase Daredevil to bounce straight back to your hand, ready to be discarded again to fuel the cycle indefinitely.
