At the beginning of each combat, any opponent may sacrifice a creature of their choice. If a player does, tap this creature and put a +1/+1 counter on it.
Each opponent in turn order may choose to sacrifice a creature, even if an opponent already chose to sacrifice a creature that combat. Desecration Demon will have a maximum of one +1/+1 counter put on it each combat, no matter how many creatures were sacrificed.
Players won't know which player, planeswalker, or battle Desecration Demon will attack, if any, when deciding whether to sacrifice a creature.
