This elegant loop relies on Ojer Taq, Deepest Foundation's replacement effect to supercharge the activation of Tooth and Claw. Because Ojer Taq multiplies each incoming token batch by three, sacrificing just two creatures to Tooth and Claw yields three brand-new 3/1 Carnivore tokens instead of the usual one. This leaves you with a surplus of bodies every single cycle, allowing you to continually feed the engine for as many iterations as you desire.
