Reception
Wizards of the Coast received overwhelmingly negative feedback from the player base about the price, the near-total breakdown of the Hasbro site on sale date, the late launch of the product, a message on the Hasbro site saying that the sale had been pushed back to October 4th, being charged multiple times, receiving order confirmations which were then cancelled/rescinded and lack of international shipping. Before the controversy began, their response was that it was an experiment and that they would let the sales speak for themselves. They supplied a limited amount of this product to ChannelFireball Events for sale at Grand Prix, but as soon as the issues with the Hasbro site were apparent, all available product for US GP events sold out immediately.

A month after the release, Wizards of the Coast sent out an apology letter due to the technical issues with completing transactions on the website.
