Lord Skitter, Sewer King + Void Attendant + Earthcraft + Conspiracy

Lord Skitter, Sewer King

Void Attendant

Earthcraft

Conspiracy

How it works

1. Activate a basic Forest by tapping it, adding .
2. 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.
3. 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.
4. Activate Earthcraft by tapping the Eldrazi Scion, untapping a basic Forest you control.
5. Activate the Eldrazi Scion by sacrificing it, adding C.
6. Repeat.

This clever loop relies on Conspiracy to rewrite the biological destiny of your entire team, forcing the Eldrazi Scion tokens created by Void Attendant to enter the battlefield as Rats. This type-shifting makes every token arrival instantly trigger Lord Skitter, Sewer King, which feeds the exact graveyard fuel that Void Attendant needs to keep the assembly line moving. Meanwhile, Earthcraft turns each newly minted Rat into a mana-generating engine by tapping it to untap your basic Forest, while sacrificing the token for colorless mana keeps your resource loop fluid.
