Overview

With Altar of Dementia, Karmic Guide, and Reveillark under the same player's control, you can sacrifice Karmic Guide to Altar, then sacrifice Reveillark to Altar to return Karmic Guide (via Reveillark's leave-the-battlefield trigger) and then have Karmic Guide's enter-the-battlefield trigger return Reveillark, restoring both creatures; repeating sacrifices of Reveillark mills cards equal to Reveillark's power each loop. Sacrifice is defined by the game rules , Reveillark can target creature cards with power 2 or less in your graveyard , and Altar mills a number of cards equal to the sacrificed creature’s power as it last existed on the battlefield .

Step 1

Begin with Altar of Dementia, Reveillark, and Karmic Guide under your control (assume Karmic Guide has power 2 or less so Reveillark can target it) and choose a player to be milled by Altar.

Step 2

Activate Altar of Dementia and sacrifice Karmic Guide as the cost; the sacrificed creature moves directly from the battlefield to its owner’s graveyard , and when the ability resolves the chosen player mills cards equal to Karmic Guide’s power as it last existed on the battlefield .

Step 3

Activate Altar of Dementia again and sacrifice Reveillark; Reveillark moves to the graveyard and its "when this creature leaves the battlefield" triggered ability goes on the stack, targeting up to two creature cards of power 2 or less in your graveyard (you may target Karmic Guide) .

Step 4

When Reveillark’s leave-the-battlefield trigger resolves it returns the targeted creature cards (e.g., Karmic Guide) from your graveyard to the battlefield; Karmic Guide entering the battlefield causes its ETB triggered ability to trigger (it triggers when it enters).

Step 5

When Karmic Guide’s enter-the-battlefield trigger resolves you may target Reveillark in your graveyard and return Reveillark to the battlefield, restoring both creatures to the battlefield.

Step 6

With both creatures back, you can sacrifice Reveillark again to Altar, repeating the sequence (sacrifice Reveillark → Reveillark LTB returns Karmic Guide → Karmic Guide ETB returns Reveillark). Each cycle mills the chosen player for Reveillark’s power as it last existed on the battlefield .

Resolution

If Karmic Guide is a legal target for Reveillark (i.e., it has power 2 or less) and you control Altar of Dementia, Reveillark, and Karmic Guide, you can create a repeatable loop: sacrifice Reveillark to Altar (mill = Reveillark’s power) → Reveillark’s leave-the-battlefield trigger returns Karmic Guide from your graveyard → Karmic Guide’s ETB returns Reveillark from your graveyard → repeat. Each cycle mills the chosen player for Reveillark’s power . Sacrifice is moving the permanent directly to its owner’s graveyard .
