You cant trade nor buy
"Note, raynos cannot sell his/her characters on the market neither publicly nor privately (has not purchased any credits)."
Hmm, i have to buy credits, in order to get more cards. seeing how trading and selling/buying is the only way to get a proper amount of cards, is there an alternative way to be able to "verify" my trustworthyness
You don't have to buy credits to buy cards from other players, but to trade and sell yes. And there is no alternative way.
Im tempted to buy some credits and get it over with. Those anyone actaully have any of those for sale or trading, that might make me bother buying creds and confirming these things.
