Note that they are exactly lv.50, not one exp above or below.It could or it could not have EVs, we really can't know we can only suppose, those are only estimations, not the real deal; but in the end we should wait and see, after all there's only 8 days left.
It would mean that they deliberately added EVs in his higher attacks while leaving the rest essentially untouched.
THAT is less likely than the attacks really being min 165.
No need to wait when its pretty straight forward, simply assuming they're not intentionally trying to trick us with these stats (wtf).
