Cloud Key's cost reduction makes Graceful Reprieve free, so Phyrexian Altar's white mana from sacrificing Eternal Witness pays for the next cast. Eternal Witness's ETB returns Graceful Reprieve to hand each loop, and the Reprieve trigger puts Eternal Witness straight back onto the battlefield — the cycle is self-sustaining. Any deck running a Saffi Eriksdotter or Sun Titan recursion package already wants three of these four pieces.

Cheaper, tighter, alternate lines

Altar of Dementia or Blasting Station slot in as the kill — the loop produces infinite sacrifice triggers but no damage or mill on its own. Strionic Resonator can replace Cloud Key if the cost reduction is unavailable, by copying the Graceful Reprieve trigger, though that demands an additional two colorless per loop and inflates the setup cost meaningfully.
