Rukarumel, Biologist + Sliver Queen + Gemcutter Buccaneer + Krark-Clan Ironworks

Rukarumel, Biologist

Sliver Queen

Gemcutter Buccaneer

Krark-Clan Ironworks

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 Rukarumel, Gemcutter Buccaneer triggers, creating a tapped Treasure token.
3. Activate Krark-Clan Ironworks by sacrificing the Treasure, adding CC.
4. Repeat.

This fascinating loop relies on Rukarumel, Biologist to rewrite the very fabric of your creature types, turning all your nontoken creatures, spells, and cards into Slivers alongside their other types. With Sliver Queen already on board providing a cheap token-generation engine, every new token enters as a Pirate thanks to Rukarumel's type-granting aura. That unexpected Pirate classification is the linchpin that lets Gemcutter Buccaneer spot the incoming token and spit out a tapped Treasure token in return. Finally, Krark-Clan Ironworks steps in to recycle those newly minted Treasures into raw colorless mana, generating a surplus that easily feeds Sliver Queen's activation cost and sets off the whole engine again for infinite creature entries and tokens.
