For a long time, Chansey was my white whale. Before trading, I had 0 Chanseys. I did ALL the events, and maybe the year they implemented trading, I got ONE. Not even a 3*.

Of course, the gyms around me were all Blissey towers.

I trading with friends until I got a 3*, and it sucked, but I loved it.

Eventually, I moved to a Mountain biome and caught a ton. I moved again and I don't know my biome, but I caught 3 or 4 wild Blisseys last year.

I'm a casual player, but I somehow managed to get an entire shiny family (the Blissey was evolved)... including a Happiny!

Still, I'm excited for this community day!
