809.1.c. It is functionally short for "Spells and abilities an opponent controls that choose me cost an amount of Power equal to [Deflect Value] more to play as an additional cost for each time they choose me." 809.1.c.1. The Power used to pay this cost may always be of any Domain. Example: A Fury spell targets an Order unit with Deflect. The Power used to pay the Deflect cost can be any Domain; it does not need to match the Domain of the spell or the target.
