Fluctuator reduces Canyon Slough's cycling cost to zero; Bone Miser converts the discard into two black mana; Escape Protocol blinks Eternal Witness for one, which returns Canyon Slough to hand and resets the loop. Every iteration draws a card, so the engine digs through the entire library while the mana accumulates.

Variations

Cheaper, tighter, alternate lines

Any other cycling land with a basic land type can replace Canyon Slough if the deck wants redundancy in the piece that feeds the loop — Sheltered Thicket and Scattered Groves cycle identically under Fluctuator. Infinite black mana and draw don't close the game alone; pair this with a Laboratory Maniac or Thassa's Oracle already in hand, or lean on the infinite ETB triggers with a damage outlet like Purphoros, God of the Forge already on the battlefield.
