Why is this card good?
Altar of Dementia is a free sacrifice outlet that doubles as a wincon, which is exactly what aristocrats and combo decks crave.
The key insight: it's a free, repeatable sac outlet (no mana, no tap), so it loops infinitely with the right pieces. Pair it with persist/undying engines (Murderous Redcap), token generators, or reanimation loops to mill all opponents out instantly. Combos like Karmic Guide + Reveillark, or any "create infinite creatures" line, end the game on the spot through Altar.
Wants it:
- Aristocrats decks (Meren, Teysa, Yawgmoth) for a no-cost sac outlet.
- Combo decks that generate infinite bodies and need a colorless mill outlet to close.
- Token decks with big creatures (mill = power, so fatties hurt).
Skip it when: your deck has no infinite engine and just wants a sac outlet for value — Viscera Seer or Ashnod's Altar usually serve better since milling opponents one card at a time accomplishes little and can accidentally fuel graveyard strategies. It's a combo finisher first, value piece a distant second.
