Ashnod's Altar
Luminous Broodmoth
AI DraftFeb 26, 2026

Ashnod's Altar + Luminous Broodmoth

Overview
When you activate Ashnod's Altar and sacrifice a creature, the sacrifice moves the creature from the battlefield to its owner’s graveyard as defined by the Sacrifice rule . That causes Luminous Broodmoth’s triggered ability to trigger (its oracle text). After the activation finishes and state-based actions are checked, triggered abilities waiting to be put on the stack are put on the stack , so Broodmoth’s trigger will be on the stack above the Altar’s activated ability (which was placed on the stack as part of the activation). The Broodmoth trigger will resolve first and return the creature to the battlefield with a flying counter (if it is a legal target for that trigger); then the Altar’s ability will resolve (producing its mana), but it will not re-sacrifice the returned creature because the sacrifice was already paid as the activation cost . See ruling clarifications: Ruling [2020-04-17].
Step 1
You activate Ashnod's Altar’s ability and pay its activation cost by sacrificing a creature; sacrificing moves that permanent from the battlefield to its owner’s graveyard as described in .
Step 2
Because the creature was put into the graveyard from the battlefield and it did not have flying, Luminous Broodmoth’s triggered ability triggers (per its oracle text).
Step 3
After the activation finishes (the cost was paid and the activated ability has been placed on the stack as part of activation), the game checks state-based actions and then places any triggered abilities waiting to be put on the stack . The Broodmoth trigger will be placed on the stack above the Altar’s activated ability.
Step 4
The Broodmoth trigger resolves first and returns the creature from the graveyard to the battlefield under its owner’s control with a flying counter, assuming the creature is a legal object to return (not a token that ceased to exist).
Step 5
After that, the Altar’s activated ability resolves (it produces {C}{C} according to its oracle text). The sacrifice cost has already been paid; the ability’s resolution doesn’t attempt to sacrifice the creature again.
Resolution
If you sacrifice a creature to Ashnod’s Altar while you control Luminous Broodmoth, the creature’s being put into the graveyard as the sacrifice (per ) causes Broodmoth to trigger. That trigger will be placed on the stack and will resolve before the Altar’s activated ability resolves because triggered abilities waiting to be put on the stack are placed after state-based actions are checked . The Broodmoth trigger returns the creature to the battlefield with a flying counter (if it’s a legal object to return); the Altar’s ability then resolves and produces {C}{C}. See Ruling [2020-04-17].
