They aren't going to add rewards to Draft. They said Draft will have a cooldown period, but no entry fee and no rewards is part of the separtion from Arena mode.
Well, that sucks. I guess they can still change that, if they see the mode fails and players are strongly demanding for rewards.
Also, i hadnt figured out how the mode works before, i thought you would simply play as many time you wanted with a deck until 7 wins (with the option of redraft), but after seeing a streamer video, apparently you just play 7 matches, doesnt matter how many are wins or losses, then it ends.
Talk about anti-climatic...
