This pokemon was attached to a random pokestop. Should I transfer it?

You could say that

Eh

Kekcleon has a 1/200 chance of appearing in pokéstops, so I’d say that’s quite an uncommon find

Its 1/200 to find in pokestops, but usually events make it easier to find.

When the pokemon actually debuted, i caught around 3 in less than an hour.

Just keep it. Kecleon isnt even a good pokemon but its still a nice flex.

I knew Kecleon was rare but not that rare
