Okay /vp/. Pokemon are suddenly real by lab experiments and your dreams of getting a cool creature happen yada yada. HOWEVER, a universal rule is applied to avoid overpopulation of Pokemon, and provide order to the world.
> Only one Pokemon per person, this Pokemon is given via egg and said Pokemon is only determined by type. This Pokemon can never be gotten rid of or traded away and must remain with you forever

Assuming that the type only affects the first-stage and there are no legendaries. Which type will you pick for the highest chance of getting a Pokemon you're satisfied with?
