Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Altar of Dementia + Visionary Augmenter

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

Altar of Dementia

Visionary Augmenter

How it works

1. Activate Altar of Dementia by sacrificing Visionary Augmenter.
2. When Visionary Augmenter dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Visionary Augmenter enters, its fabricate ability triggers, putting a +1/+1 counter on it.
4. Resolve the Altar of Dementia ability.
5. Repeat.

This clever loop relies on Isilu, Carrier of Twilight—the night-facing side of Eirdu, Carrier of Dawn—to grant persist to your other nontoken creatures, allowing them to keep returning from the graveyard after being sacrificed to Altar of Dementia. Whenever Visionary Augmenter enters the battlefield, its fabricate 2 ability triggers to place two +1/+1 counters on it, which immediately neutralize the -1/-1 counter it received from persist via state-based actions. This resets the creature so it can safely be sacrificed to Altar of Dementia all over again, milling your opponent out in the process.
