With Niantic officially tweeting to the world that “stay tuned for more”, we might actually expect something groundbreaking updates from Niantic in the upcoming weeks. As it is cold out there we might actually expect an increased spawn rate for ice types. A strong Lapras would be a good counter for those overpowered Dragonites.
You would be better off is you spend the same on incubators and hatch more eggs in less amount of time and in turn gain more XP so that you get to encounter stronger Pokemon in the wild which in a way will help you to level up at a faster rate.
