Yes, as previously stated, just the dex for now. If another decentralized exchange shows up for counterparty, that would be great.  While we've reached out to other exchanges, there's only a few that take counterparty and they don't take requests (tux) or respond to requests (like bittrex or poloniex).

While I love counterparty because it's easy to develop on and use, there might come a point where we need to move to another type of token on a different blockchain. Simply because people want to buy the tokens and cards using Eth and Bitcoin and the counterparty DEX makes it hard to do that since you have to buy XCP before hand. So it's not easy for players... We certainly wouldn't change anything without a thoughtful token conversion process, plus with the game rewards in Bitcoin and the game engine in bitcoin, moving to something like Ethereum would be a fundamental change that would set back things considerably.
