503.8. If an ability causes a player to make a choice as a copy comes into play, the copy will "remember" that choice and continue to use it for its abilities if appropriate. If the choice is not appropriate, it is considered to be "undefined." If an ability refers to an undefined choice, that part of the ability has no effect. Example: A Vesuvan Doppelganger comes into play as a copy of Chameleon Spirit, and the Doppelganger's controller chooses blue. Later, the Doppelganger copies Quirion Elves. The Elves has the ability, "{T}: Add one mana of the chosen color to your mana pool." If the mana ability of the Doppelganger is played, it will produce blue mana. Example: A Vesuvan Doppelganger comes into play as a copy of Caller of the Hunt. Caller of the Hunt reads, in part, "As Caller of the Hunt comes into play, choose a creature type." The Doppelganger's controller chooses Goblin. Later, the Doppelganger copies Quirion Elves. If the mana ability of the Doppelganger is played, it will fail to produce any mana. It won't produce Goblin mana.	503.8a. If an ability causes a player to "choose a [value]" or "name a card," and a second, linked ability refers to that choice, the second ability is the only ability that can refer to that choice. An object doesn't "remember" that choice and use it for other abilities it may copy later. (This is a change from previous rules.) If an object copies an ability that refers to a choice, but either (a) doesn't copy that ability's linked ability or (b) does copy the linked ability but no choice is made, then the choice is considered to be "undefined." If an ability refers to an undefined choice, that part of the ability won't do anything. Example: A Vesuvan Doppelganger comes into play as a copy of Chameleon Spirit, and the Doppelganger's controller chooses blue. Later, the Doppelganger copies Quirion Elves. The Elves has the ability, "{T}: Add one mana of the chosen color to your mana pool." Even though a color was chosen for the Doppelganger, it was chosen for a different linked ability. If that mana ability of the Doppelganger is played, it will not produce mana.
