Cloudform seems innocuous enough. A 2/2 protected flier for 3. Not really constructed playable, I guess. Unless, of course, you want the devotion. Maybe in some situations, it would be good to have a Master of Waves with hexproof, although in that case you don’t get the tokens, of course, but if another Master brought in the tokens, this one could keep them alive.
Block Constructed is always a nice predictor of future Standard. What can we learn from Pro Tour Journey Into Nyx?
