I got to play some Into the Emerald Dream cards early in the latest Theorycrafting event, and Starship Armor Demon Hunter was one of the scariest decks I played, because it can gain seemingly endless armor.

Power Level Estimate: Too early to say because this was from a theorycrafting event, but this deck seems like it could create a lot of problems in the meta with its absurd defensive potential.
