Because you love Grass types, I want to share a spoiler-free tip when you start exploring the new Pokemon. There is a mono Grass type with access to Leaf Guard and Oblivious. Catch one with Oblivious if you can. It’s name ends with the letter -t.
Ooh, how cryptic. And what an odd ability to prefer. I suppose Oblivious must be replaced by something else as the Pokémon evolves…? I look forward to finding out.
