Aluren lets Saffi Eriksdotter and Eternal Witness cast for free, so the sacrifice-and-recur loop between them costs nothing to sustain. Altar of Dementia is the kill condition built into the engine itself: each iteration mills a target equal to Eternal Witness's power, which grinds every opponent out in the same turn. The combo lives in Saffi Eriksdotter as commander or any Selesnya value shell that already wants Aluren and Eternal Witness as independent pieces.

Prerequisites

Steps

Activate Saffi by sacrificing it, targeting Eternal Witness.
Activate Altar of Dementia by sacrificing Eternal Witness.
When Eternal Witness dies, Saffi triggers, returning it from your graveyard to the battlefield.
When Eternal Witness enters the battlefield, it triggers, returning Saffi from your graveyard to your hand.
Resolve the Altar of Dementia ability from step 2, causing target player to mill cards equal to Eternal Witness's power.
Cast Saffi by paying due to Aluren.
Repeat.

Result

Infinite death triggers; Infinite ETB; Infinite LTB; Infinite mill; Infinite sacrifice triggers; Infinite self-mill; Infinite storm count

Cheaper, tighter, alternate lines

Altar of Dementia is the cleanest built-in closer, but the infinite death and ETB triggers support any payoff that doesn't require mana — Impact Tremors or Zulaport Cutthroat finish the job if the Altar is removed. Karmic Guide can substitute for Saffi Eriksdotter in the recursion role, though it costs 2 more mana and won't cast for free under Aluren unless your commander grants it creature types or you have a separate cost reducer.
