Sacrifice Outlet

Permanents with an activated ability whose cost includes sacrificing a creature, letting you funnel bodies into value on demand. Viscera Seer scries, Ashnod's Altar produces colorless mana, Phyrexian Altar fixes any color, Carrion Feeder grows itself, and Goblin Bombardment pings any target. These are the engines aristocrat decks build around, turning tokens and dying triggers into a repeatable loop. Distinct from sacrifice.aristocrat, which drains opponents on each death rather than providing the sac button itself, and from sacrifice.fodder, which covers the cheap bodies fed into these outlets. Cards that force opponents to sacrifice belong with edict-style removal, not here, since this concept is about you choosing what to sac as a cost.
