Changes observed in game files:
All of Suncrest troops have now gained a spell, and some have gained traits..
Next (after Suncrest) kingdom's troops appeared. They are currently slated for 2017-05-26. Only troop and spell names are currently available, not even colors are set properly (they're all mono-red regardless of rarity).
Release schedule after new kingdom is shifted forward by one week to fit the new kingdom.
May's mythic gained a third trait, and June's mythic appeared.
Full spell and trait info for the new GW troop rewards.
Full details will follow later, or per request, as that's a lot of info. In the meantime, behold next week's troop:
