My flygon OHKOed a tyranitar in Pokemon showdown, and I thought, why is tyranitar in OU and flygon in uber? Against each other, flygon is obviously superior. (I also OHKOed a charizard Y with stone edge..so explain about that too plz
Why is Flygon in UU if it can beat Tyranitar / Charizard?
Because that's not how tiers work.
Also Flygon has significantly worse niches both of those in OU. Those two mons create weather.
this is common sense
