Recently announced was the upcoming duel deck Jace vs Vraska. This duel deck takes us back to the Ravnica plane one last time for a final showdown. Jace vs Vraska will be released March 14, 2014.
Jace’s deck appears to be mono blue giving Jace, Architect of Thought. Architect of Thought may not be as impressive as Jace, The Mind Sculptor but he is strong in his own way. The reason why Jace’s hood is down lately (and even tidy hair) is unknown.
Vraska’s deck features Vraska herself and it appears to be Golgari themed (green black), perhaps a Gorgon tribal. Vraska’s deck would welcome Jace’s milling (if it is his deck’s focus) as a Golgari deck fights better on a healthy graveyard.
If you haven’t already figured out the release pattern, we would expect two of either Elspeth, Ashiok, Xenagos or a planeswalker(s) from subsequent Theros set to be featured in the duel deck for next year. The last duel deck that featured Jace was Jace vs Chandra.
