This is a great guide, something that any new player should definitely read over since these are extremely valuable techniques. Old players could also do with reading it over sometimes, myself included.
Most of the other reviews covered it pretty well but I think in certain areas there could definitely have been a bit more detail covering certain points.
You covered SH FF and Instant Dashing extremely well giving good a good explanation and how to perform, personally I'd expand on the application of both during game, you did touch but I'd go through it a little more.
And you definitely want to add some more to the Edge guarding section, it was the only part that stood out as lacking and I think you could definitely cover a lot with it since its such a core element of the game.
Otherwise a really great guide, even with potential to improve this guide is still extremely useful so thank you for doing it!
