promo cards are special cards given to players upon winning a Pokemon card tournament... so yes

Yes!
You can use them in official tournaments and such, but they aren't worth much if you try to sell them
well, actually you can but not in tournaments.
Only in China compadre! =]
A promo is a promotional card, ie, one that does not come from a booster pack set, it's specially made for something else. So for example, major tournament prize cards, the cover card in a booster pack tin, the cards given away at the Pokemon movies, etc, are all Promo cards.
As long as the card is not on the forbidden list, then you can use it in a tournament. There is no set rotation, cards from every set are legal.
There are many different types of tournaments. Tournaments can be involved with sports. Tournaments can also be involved with games, such as chess or cards. Tournaments can also be academic.
To get promo codes you have to buy a toy.
you can print them off of www.pokebeach.com but you won't be able to use them in tournaments, they're called proxiis
There are official copies of obelisk and the winged dragon of ra. Those may be used in tournaments. If your Egyptian god has a colored back, you may not use it
