Lord Skitter, Sewer King + Void Attendant + Pitiless Plunderer + Maskwood Nexus

Lord Skitter, Sewer King

Void Attendant

Pitiless Plunderer

Maskwood Nexus

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 Maskwood Nexus, 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.

This ingenious loop transforms the passive identity-shifting of Maskwood Nexus into a self-sustaining engine of creation and tribute. With the Nexus rewriting every creature you control to be every type—including a Rat—each Eldrazi Scion birthed by Void Attendant instantly triggers Lord Skitter, Sewer King to strip away an opponent's graveyard and stock the exile zone for future activations. When you sacrifice that Scion for mana, Pitiless Plunderer steps in to generate a Treasure token, refunding the exact resources needed to fuel Void Attendant's ability once more.
