Topic for events on Pokemon event that you can get via wi-fi.
Newest one is the Route: Winner's Path, where you can catch pokemon based on your type, as my friend and I have experinced.
I used Rotom, an Electric/Ghost type and I have seen Bronzor and Duskull so far.
My friend used Squirtle and has seen Magikarp and Horsea.
We used the same Route, Winner's Path.
So experiment, use different pokemon.
