Wording changed702.119bDetails
You choose which creature to sacrifice as you choose to pay a spell's emerge cost (see rule 601.2b), and you sacrifice that creature as you pay the total cost (see rule 601.2h).Emerge from [quality] is a variant of emerge. "Emerge from [quality] [cost]" means "You may cast this spell by paying [cost] and sacrificing a [quality] permanent rather than paying its mana cost" and "If you pay this spell's emerge cost, its total cost is reduced by an amount of generic mana equal to the sacrificed permanent's mana value."
