I finally got my next gold badge! Purifying 500 Pokemon definitely took a while and cost a ton of stardust (Over 1 million) but it was definitely worth it to get closer to all Platinums. I need to purify another 500 so that’s going to take an extremely long time but I’ll have finished doing that at some point. In the meantime I maxed out several more Pokemon. Just one more for Sinnoh (Spiritomb) and then you can expect another Pokemon Go update coming up. Gotta keep catching them all!
