I'm also new to the splinter lands, and to all the NFT maddness, the friend that got me into this used to rent powerful cards in order to win ranked batles and gain DEC, but since the DEC earning drop a few days ago I don't think it s longer a good idea. I would also advice the new adventurers to seek for good long term rent offers, to get their hands in other cards the initial pack doesent have. The creeping ooze is just awesome.
