Fluctuator drops Slippery Karst's cycling cost to zero; Bone Miser converts the discard into two black mana, and Escape Protocol pays one of that mana to blink Eternal Witness, which returns the Karst to hand. The loop is self-sustaining — each iteration draws a card, refills the Karst, and nets one black mana after the blink cost, running until the deck is empty.

Result

Infinite black mana; Infinite card draw; Infinite ETB; Infinite LTB

Variations

Cheaper, tighter, alternate lines

Barren Moor or any other black-aligned cycling land substitutes for Slippery Karst if the forest type is irrelevant, but Slippery Karst is the cleanest fit since Bone Miser only demands a discard, not a specific card type. The loop produces infinite mana but needs a sink — Walking Ballista or Exsanguinate converts the black mana into a kill, while Thassa's Oracle closes on the infinite draw alone.
