Enchant player Whenever enchanted player is attacked, create a Gold token. Each opponent attacking that player does the same. (A Gold token is an artifact with "Sacrifice this token: Add one mana of any color.")
原文Curse of Opulence's triggered ability resolves after attackers have been declared. Any costs to attack must have already been paid before the attacking player creates the Gold.
原文A player is attacking another player if they control a creature that's attacking that player. If no creatures are attacking the enchanted player as a Curse's ability resolves (most likely because they've left the battlefield), only the Curse's controller performs its actions.
