- Wizards of the Coast2015-09-28Thirst for Knowledge was unrestricted in vintage on September 28, 2015. In 2009, blue-based artifact decks were dominating the format. There were not many options of cards to restrict, and we chose Thirst for Knowledge. This led to a much healthier metagame. However, six years later, a lot of cards have been added and the metagame is very different. The former dominating strategies are barely seen at all; the reason for the restriction is no longer evident.
