Displacer Kitten blinks Eternal Witness every time a noncreature spell resolves, which means each Snap cast returns Lotus Petal and then Snap itself back to hand through two consecutive Witness triggers. Two untapped lands that produce at least 1U keep the loop self-sustaining — Lotus Petal contributes the extra colored mana each cycle, netting one colored mana per iteration while clearing all opposing creatures via Snap's optional bounce.

Recipe

How it works

Prerequisites

You control up to two lands that can tap to produce at least . Creature That Can Be Cast Using One Colored Mana

Steps

Activate up to two lands by tapping them, adding at least .
Cast Snap by paying .
Displacer Kitten triggers, blinking Eternal Witness.
When Eternal Witness enters the battlefield, it triggers, returning Lotus Petal from your graveyard to your hand.
Resolve Snap, returning the creature that can be cast using one colored mana from the battlefield to your hand, and untapping two lands you control.
Cast Lotus Petal by paying .
Displacer Kitten triggers, blinking Eternal Witness.
When Eternal Witness enters the battlefield, it triggers, returning Snap from your graveyard to your hand.
Activate Lotus Petal by tapping and sacrificing it, adding one mana of any color.
Cast the creature from your hand by paying its mana cost.
Repeat.
You may instead bounce any creature you don't control to its owner's hand instead of bouncing the generic creature, as long as your opponents control creatures, and net one colored mana per loop.

Result

Infinite LTB; Infinite ETB; Infinite storm count; Infinite magecraft triggers; Near-infinite colored mana; Return all creatures you don't control to their owner's hand; Infinite mana lands you control can produce; Infinite untap of lands you control

Variations

Cheaper, tighter, alternate lines

Any one-mana creature serves as the fifth piece Snap bounces and recasts; Grim Monolith or Mana Vault substitutes for the land requirement if the mana base is tight. The loop delivers infinite ETB and storm count but needs a payoff — Thassa's Oracle wins on empty library, Aetherflux Reservoir closes on storm count, and Blue Sun's Zenith or Stroke of Genius converts the mana into a mill kill.
