Tower Winder casts itself from the graveyard by discarding Command Tower; Kheru Goldkeeper converts each discard and each enters-the-battlefield trigger into a Treasure, netting two Treasures per loop. Tower Winder then returns Command Tower to hand on entry and dies to Altar of Dementia, milling a target, before the two Treasures recast Tower Winder to start again. Six sits in the command zone as the glue — without it enabling the graveyard cast, the loop doesn't exist, so this is firmly a Six deck.

Cheaper, tighter, alternate lines

Altar of Dementia is the only mill sink listed in the steps, but once the engine is running, any free sacrifice outlet that generates a payoff — Pitiless Plunderer doubling the Treasure output, for instance — can replace it if mill isn't the preferred kill. The loop is tight on mana with exactly

required each iteration, so any disruption to the Treasure generation, such as a Collector Ouphe, collapses it immediately.
