This engine relies on the incredible token-multiplying power of Ojer Taq, Deepest Foundation to turn a modest sacrifice into a massive surplus. When you activate Goblin Warrens by sacrificing two Goblins for its cost, Ojer Taq steps in to triple the resulting output, yielding nine new Goblin tokens instead of just three. You can then feed just three of those freshly minted tokens to Skirk Prospector to recoup the exact amount of red mana needed to keep the cycle going. Because every single iteration generates a net positive of tokens, you can loop this process indefinitely to fuel endless sacrifice triggers, death triggers, and a mountain of red mana.
