Woh, that craftsman looks quite sexy. Despite the comparison with Merchant Guild, I think you should consider upping it to +2 coins.
EDIT: the big difference with your previous version is that, if you want to gain a card the second time you play Craftsman, you have to buy 2 cards the first time you play it, otherwise you will have to wait until your third Craftsman. The other big difference is that, after that first craftsman, you may be able to gain a 5$ with each Craftsman, as long as you play around it.
The big difference with Merchant Guild is that you have to wait until the next time you play Craftsman to use the tokens, while MG can use them whenever, and that Craftsman can only use tokens to gain 5$ cards, while MG can use tokens to get Provinces and whatnot.
