Congrats! Nice catch.
I would be running around telling the world about it.
My luckiest would be a time, not a specific catch and has to be the Valentines event.
My neighbourhood was flooded with the big beautiful pink lady...and I made the most of it.
The first morning of the event, I went for my usual early morning walk of about 1.5kms and came home with 6 Chansey - including a lvl28 93% IV (perfect att and def stats).
From that moment on, I knew the event was going to be kind to me.
