Krenko, Baron of Tin Street + Pitiless Plunderer + Carrion Feeder

Krenko, Baron of Tin Street

Pitiless Plunderer

Carrion Feeder

How it works

1. Activate a Treasure by tapping and sacrificing it, adding .
2. Krenko triggers, causing you to pay to create a 1/1 Goblin creature token with haste.
3. Activate Carrion Feeder by sacrificing the Goblin token.
4. When the Goblin dies, Pitiless Plunderer triggers, creating a Treasure token.
5. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
6. Repeat.

This loop relies on a clever perpetual motion engine fueled by death and recycling. You start by sacrificing a Treasure token for mana, which triggers Krenko, Baron of Tin Street to turn that spent artifact into a hasty Goblin token by paying the resulting red mana. Carrion Feeder then steps in to snack on that newly minted Goblin, growing larger with a +1/+1 counter each time. Finally, the demise of your Goblin ensures that Pitiless Plunderer triggers to replace the sacrificed Treasure, letting you feed the loop infinitely.
