Someone posted his deck on reddit:

I have no idea but it looks like a good deck. Lot's of control combined with the elusive faerie's to gather Ember.

These are on tabletop simulator, I believe there are two decks so far, the same guy that did a youtube video on that deck did another video on the other.
