Alright, zygard gets an increase in HP when it goes 100, and to compensate gets a 50% recovery in HP. While this is obviously a 1 mon gimmick, what if now Pokemon got an increase in hp when they mega evolve? Would they get a free recover, would it only matter if they mega as soon as they're out? Or maybe they can just change the HP and you have the same HP after you mega relative to what you had before, as in 100%hp is 233, mega's hp is 256, so if you mega at full hp you go 233 to 256?
