This is hilarious. Without remembering your card at all, I made mine called Shipwright. I guess the obvious connection from Barge to Merchant Guild is people building ships.
Exotic Goods feels too much like Garrison. But I like Garrison! And it's sad that it's under Tent. So who cares.
I feel like the +2 Cards is out of place here. You can't use it as a draw card because of the duration part. It's probably still good enough without that? You could make the +1 Buy be on both turns; I'd get annoyed if I was just getting this for the +Buy and I had to get two copies.
Also "until the end of your next turn" probably means it won't be discarded until the end of the player to your left's turn after that, since that'll be after you discard and draw your new hand.
