Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Grim Poppet + Bloodflow Connoisseur

Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Grim Poppet

Bloodflow Connoisseur

How it works

1. If Grim Poppet has any -1/-1 counters on it, activate it by removing a -1/-1 counter from it.
2. Repeat step 1 as necessary until Grim Poppet has no -1/-1 counters on it.
3. Activate Bloodflow Connoisseur by sacrificing Grim Poppet.
4. When Grim Poppet dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. Resolve the Bloodflow Connoisseur ability.
6. Repeat.
7. Resolve all Grim Poppet abilities, putting infinite -1/-1 counters on any number of creatures.

This clever loop relies on the transforming front and back sides of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight to grant persistent immortality to your board, letting Isilu give Grim Poppet the persist ability it needs to keep coming back. Once Grim Poppet is in play, you can strip away its counters using its own ability to spread -1/-1 misery around before feeding the creature to Bloodflow Connoisseur. Each time Bloodflow Connoisseur sacrifices Grim Poppet, persist brings it right back with a fresh -1/-1 counter and a clean slate, allowing you to fuel Bloodflow Connoisseur's growth infinitely while locking down the opposing board.
