I could start with the obvious: I hope for Lorenzo. He seems to publish 1 project + 1 Ravn every year and we know that the next project seems to be a new Ravn pair, so maybe the next big project could be the UC 2019 deck? Gemini is my favorite deck and was the best designed deck I had ever seen, until The House of the Rising Spade was released. Also Lorenzo has not designed a UC annual deck, so now would be a great time

As for other possible names I would like to see: Sunish, Passione team, Kirk Slater and montenzi. As a wild card: A custom deck produced with the VXD's technology.
Let me know your thoughts!
