Lord Skitter, Sewer King + Void Attendant + Pitiless Plunderer + Conspiracy

Lord Skitter, Sewer King

Void Attendant

Pitiless Plunderer

Conspiracy

How it works

1. Activate Void Attendant by paying 1 and putting a card an opponent owns from exile into their graveyard, creating a 1/1 Eldrazi Scion creature token.
2. When the Eldrazi Scion enters the battlefield as a Rat due to Conspiracy, Lord Skitter's first ability triggers, exiling a card from an opponent's graveyard.
3. Activate the Eldrazi Scion by sacrificing it, adding C.
4. When the Eldrazi Scion dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
5. Activate the Treasure by tapping and sacrificing it, adding .
6. Repeat.

By casting Conspiracy and naming "Rat," you completely rewrite the biological destiny of every creature you own—turning every token you make into a Rat that fuels Lord Skitter, Sewer King every time it enters the battlefield. That endless stream of fresh bodies feeds directly into Void Attendant, which eagerly recycles exiled cards to spit out Eldrazi Scions while converting your mana inputs into an endless loop. Every time those Scions inevitably bite the dust, Pitiless Plunderer steps in to cash in their demise for brand-new Treasure tokens, providing the exact green mana needed to keep the Void Attendant's activation cost perpetually paid.
