I'm not sure if this is a mistake, or if it's not there on purpose.
The thing is, in the main site's trainer guide, when naming the best moves for a certain type, you say that the best ones for grass are Giga Drain, Razor Leaf and Magical Leaf. My point is, you don't mention Leaf Blade. I'm not sure you overlooked it or didn't write it down on purpose since only a species of pokemon can learn it.
Here's the link, as per recommended, although I'm pretty sure you don't need it:

Once again, I'm really sorry if this is no mistake at all... really.
