The Dragon Lord
Why no Axew specific egg hatches during the Dragon event? : (
We can only guess at the answer. Most likely is that Niantic still wants to keep Axew as nearly unobtainable for the foreseeable future so that they can market it later on down the line in an attempt to get us to spend more money. More specifically, people (for some unfathomable reason) were already willing to spend money on incubators to hatch a Deino, so if they're going to spend money anyways, no reason to bring in Axew as well, when it can get its own event later on down the line that people will spend even more money on.
