This one is different, however. Unlike Valor, Kraken, and Shadowdiver, Augmented Stalker is from Nekki's own concept art. One of their newer concept arts at that, along with that Night Warrior and Star Chaser. They had been following the established name with Star Chaser, so isn't it logical to think that this set will be named Augmented Stalker? Not even a fan-nickname, this one is "official" (for the lack of better word), and they retconned it.

And don't forget that bonus name = set name. So, in this case, this set bonus is Future Keeper. Thus, the set is named, Future Keeper.
