Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Grim Poppet + Megatog

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

Grim Poppet

Megatog

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 Megatog 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 Megatog ability.
6. Repeat.
7. Resolve all Grim Poppet abilities, putting infinite -1/-1 counters on any number of creatures.

This clever loop turns Grim Poppet and its built-in reservoir of -1/-1 counters into a devastating engine of attrition, fueled by Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight granting the puppet a persistent safety net via its back face's bestowal of persist. By using Grim Poppet's activated ability to strip away its own counters, you can safely feed it to Megatog's sacrifice outlet without losing the creature entirely; the persist trigger brings it right back to the battlefield with a single -1/-1 counter ready to be removed all over again. As the puppet repeatedly perishes and returns, Megatog grows to towering proportions while generating an endless stream of sacrifice, death, and entry triggers to lock down the board and wipe out your opponents' creatures.
