Sliver Queen + Gemcutter Buccaneer + Krark-Clan Ironworks + Conspiracy

Sliver Queen

Gemcutter Buccaneer

Krark-Clan Ironworks

Conspiracy

How it works

1. Activate Sliver Queen by paying 2, creating a 1/1 Sliver creature token.
2. When the Sliver enters the battlefield as a Pirate due to Conspiracy, Gemcutter Buccaneer triggers, creating a tapped Treasure token.
3. Activate Krark-Clan Ironworks by sacrificing the Treasure, adding CC.
4. Repeat.

This brilliant loop transforms Sliver Queen into an engine of continuous creation by fundamentally rewriting your creature types with Conspiracy, turning every new token into a Pirate. That type change is what allows Gemcutter Buccaneer to see each arriving Sliver and generate a fresh Treasure token every time. You then feed those Treasures directly into Krark-Clan Ironworks, converting them into the colorless mana needed to pay Sliver Queen's activation cost and keep the chain going indefinitely.
