Mana Geyser front-loads the red mana by taxing opponents' tapped lands; Devastating Onslaught spends six of it to create two haste Eternal Witness tokens, which immediately return both sorceries to hand. The loop demands ten tapped lands as a floor — reliable in the late game or against greedy mana bases, fragile in faster pods where opponents may not have reached that threshold by the time this comes online.

How it works

Prerequisites

Opponents control at least ten tapped lands.

Steps

Cast Mana Geyser by paying , adding for each tapped land your opponents control.
Cast Devastating Onslaught by paying , creating two token copies of Eternal Witness with haste.
When the Eternal Witness tokens enter, they trigger, returning Mana Geyser and Devastating Onslaught from your graveyard to your hand.
Repeat.

Result

Infinite LTB; Infinite ETB; Infinite sacrifice triggers; Infinite death triggers; Infinite storm count; Infinite red mana; Infinite creature tokens with haste; Infinite magecraft triggers

Temur Sabermage or Surrak Dragonclaw builds are the natural homes, using haste enablers to push the tokens into combat once the loop is assembled. Goblin Bombardment or Altar of Dementia converts the infinite token stream into a table kill — without a sac outlet or reach spell already on board, infinite tokens with haste are the engine but not the finish.
