cr:1.8.7
If an effect refers to the value of a property, it infers the existence of the property as well as its value. If an object does not have that property, it does not meet the condition of the existence of the property and thus the condition of the value of the property.
Example: Harmonized Kodachi has the text “If you have a card in your pitch zone with cost 0,” which can be interpreted as “While you have a card in your pitch zone with the cost property and the value of that property is 0.” This means a card without the cost property, such as Heart of Fyendal, will not satisfy the condition if it is in the pitch zone.
Example: Find Center has the text “. . . this can’t be defended by cards with cost less than the number of chain links you control,” which can be interpreted as “this cannot be defended by cards with the cost property, if the value of the cost property is less than the number of chain links you control.” This means cards without the cost property, such as Ironrot Helm, would be able to defend the attack.
Example: Mutated Mass has the text “This card’s {p} and {d} are equal to twice the number of cards in your pitch zone with different costs,” which can be interpreted as “This card’s {p} and {d} are equal to twice the number of cards in your pitch zone with the cost property, that have different costs.” This means cards without the cost property, such as Heart of Fyendal, will not satisfy the condition (and be included in the calculation) if it is in the pitch zone.
