I'd like to share something with you.

As of fifteen minutes ago, I just completed my goal of catching Pansear, Panpour, and Pansage in the Lostlorn Forest.

Not easy, because all three only appear in rustling grass, and there's a crazy trainer there who challenges you EVERY time you enter the place, no matter how strong a trainer you are.

I caught Pansage last, which was a little frustrating because it was the one I needed the most. I hadn't gotten a good Grass yet.

All it took were a lot of Max Repels, some luck, and a LOT of patience. That last one is the key to hunting for a rare Pokemon. If you're searching for a rare Pokemon, you have to keep reminding yourself that it's there somewhere, and you have to keep at it until you find it.
