Me and my friend got several Planeswalker deck sets through the free promo that Wizards had a while ago. Unfortunately, we have 2 red and black decks but no green or white decks. I will be happy to trade my extra red and black decks for either green or white decks if anyone would like to swap. Shipping should be low since we use USPS printed materials option and the decks are pretty light. My decks are sealed and have not been opened. OP.
