Smash Legend
i'd probably still nair it, or bair on reaction. but make sure to note what spin dash they do, as side-b can be cancelled by shield jsut after they release b, and aerial down-b spindash cancels by shield as soon as they touch the ground, both of these are used to get a grab and u-throw you, for 13%, its like sonics main form of damageAnd don't forget the counters every so often if you think they will spin dash right into you, which they will at times
