>>41189418I have him in my notes but I forgot to mention it. Probably because I don't have a good pic of Gigantamax tornado snek. It think your thoughts on it suffice: the special defense boost is probably more useful than trapping the opponent in for four-five turns.
One thing to be said about G-Max Sand Blast though - if you're dastardly and run a Minimize set on this one, you have to watch out for Heavy Slam, which always hits for double damage on Minimized targets, especially with its wider distribution this gen as a TR. Dynamax and Gigantamax Pokemon are immune to weight-based moves. Hence you can lure a potential counter and then trap it and destroy it.
