Oh yeah, something I did not mention in my guide that I just thought of to mention now is that Sand Tomb cancel mixups are something all Garchomp players should incorporate into their play if they haven't already. Sand Tomb canceling I'm pretty sure gives you more potential mix-up options than just about anything else in Garchomp's moveset. And mixups are a pretty powerful thing really.
