Celestial Dawn The mirage printing of the card doesn't have the bit about colorless mana. But I assume it gets that part retroactive. Do I understand this card right? If I have, for example, these lands:
They all become plains and only produce one W and it can be used to pay mana of any color I want? Do they revert back to their original state when Celestial Dawn is no longer in play? And all the cards in play, in my deck, etc all are white cards while this is in play but their casting costs remain the same? And so if I were to have Celestial Dawn in play it maximizes my ability to cast anything I could draw. Assuming I understand this card correctly. Thanks.
All cards are played as though their Oracle wording was printed on them. What is actually printed on the card is not relevant. So all versions of a card (as identified by name) play the same.
While Celestial Dawn is on the battlefield under your control, all your lands are just Plains. They have no other land type, and also lose any other abilities, they can only tap for one white mana. This is what happens when any land is given a basic land type without the phrase "in addition to" or something similar. Nonbasic lands do remain nonbasic though, nonbasic Plains.
You can spend white mana as if it was mana of any color, yes. If you somehow get nonwhite mana into your pool, it can be spend as colorless mana. All the cards become white, but a color change does not change mana costs. A Runeclaw Bear's mana cost will still be 1G even under CD, and even though you can play it for WW. Invert the Skies will do nothing if you pay for it only with white mana. And you still could not cast Kozilek, the Great Distortion unless you somehow get nonwhite mana or colorless mana. But basically yes, you no longer have color issues to play your stuff.
CD's effect ends when it leaves the battlefield, this can happen even during the resoluion of a spell or ability (if it gets destroyed and then the spell/abilty does something else afterwards, that something else happens when your cards are no longer white and your lands are no longer Plains).
