134.2.e.6. Power of a domain corresponding to a card’s own Domain is not represented by a symbol, but appears in these rules similarly to other symbols. Its shorthand is [C]. 134.2.e.6.a. When a [C] shorthand is printed on a card as reminder text, it assumes that card’s usual Domain , but it still means “one Power of this card’s Domain .” 134.2.e.6.b. A [C] shorthand on a card with no Domain or with multiple Domains is processed as [A] instead.
