I actually think that the kayna numbers were diminishing and the monsters trapped the last one in amber. Then all the fire types forgot the ways of the fire type and evolved into the monsters we see today like Krillby-> Reedling as the fire type was lost. If they had to evolve into a monster that was allready there they would become the rare.
