Krenko, Baron of Tin Street

Biotransference

Skirk Prospector

How it works

1. Activate Skirk Prospector by sacrificing another Goblin, adding .
2. When the Goblin dies, Krenko triggers, causing you to pay to create a 1/1 Goblin creature token.
3. Repeat.

This brilliant loop transforms your entire goblin horde into a self-sustaining mana engine, legal in Commander, Legacy, Oathbreaker, and Vintage. Biotransference acts as the crucial foundation here, making your creature cards and spells into artifacts so they mesh seamlessly with Krenko, Baron of Tin Street's triggers. By sacrificing a goblin to Skirk Prospector for mana, you feed Krenko's ability; the dying goblin triggers Krenko to let you pay that exact mana to generate a fresh 1/1 Goblin token with haste. Because Biotransference turns that new token into an artifact creature as well, it loops effortlessly for infinite sacrifices, death triggers, and enters-the-battlefield effects.
