There's a small error in the section dedicated to Nattorei. It mentions that Leftovers and Rest are the only ways for Nattorei to recover HP. Leech Seed is very common on Nattorei, and even if it wasn't, it should still be mentioned.
Probably just nit-picking, but it was something I saw. Great issue, very informative.
Edit: Oh, and in the Type Analysis section, when talking about Terakion, it's mentioned that only Claydol and Goruggu resist Fighting/Rock together. Nidoking/Nidoqueen resist that combination as well.
