Quote from Urabrask »So with the planeswalker decks, Chandra and Teferi are confirmed as planeswalkers in the set, right?
We're significantly pulling back on how often the Gatewatch will appear as planeswalker cards. It will still happen when the story calls for it, but far less often. For example, for all of 2017 and 2018, only a handful of planeswalker cards will be Gatewatch members, and that's including in Planeswalker Decks, where they'll appear slightly more often.
So with Jaya being on board I'm thinking Chandra will only appearere as a planeswalker deck walker and Jaya will be in the main set, so the set walkers will be (IMO) Liliana, Karn, Teferi and Jaya.
