Lord Skitter, Sewer King + Void Attendant + Earthcraft + Arcane Adaptation

Lord Skitter, Sewer King

Void Attendant

Earthcraft

Arcane Adaptation

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 Arcane Adaptation, 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 engine transforms the colorless mana of the Eldrazi into a self-sustaining loop by weaving together type-shifting, graveyard interaction, and land untapping. With Arcane Adaptation naming "Rat," every token produced by Void Attendant instantly gains that creature type, which in turn triggers Lord Skitter, Sewer King to continuously exile cards from your opponents' graveyards. Meanwhile, Earthcraft allows you to tap those newly minted Eldrazi Scion tokens to untap your basic lands, fueling Void Attendant's activation cost and generating an endless cycle of enters-the-battlefield, sacrifice, and mana triggers.
