Silver, Gold and Diamond cards works the same as Normal cards when playing (this is not a pay-to-win game) but if you win with a deck composed of framed cards you earn additional credits. A gold card can be converted to any other silver card and three copies of the same gold card can either be converted to a Diamond version of the same card (which you will be able to sell for real money) or any other gold card.
