Welcome to this thread. As well all know, the card trading will end up on Sunday, and then after that, we will have a stop of a week, before this becomes possibly permanent, but not with the rate of this week.
So, I decided to create this thread, to muse and commemorate about this card trade fever week of the first week of April, with Sunday being April Fool's. Indeed, you might call this too early, but I don't care. Anyway, back to the topic, you can talk about anything, like posting your deck, boasting what you have, talking about the past and future of this new feature, etc.
Also, i created a Cards Against NS game to countdown toward the end of this week. The link is here: https://www.nationstates.net/page=cardgame/gameid=8540
