If your opponent shoots RSMS non-aggressively (simple banking shot or straight shot), shoot your blade right on the edge of the tornado ridge. Pretend that the inside of the stadium is a clock-- if you're shooting in left spin, aim for the 3:00 (right-hand) side of the ridge. If using right spin, aim for the 9:00 (left-hand) side. This will cause your blade to breeze right past RSMS and spin madly around the ridge in seemingly useless circles. However, by the time your blade gets tired of circling, RSMS will have lost a great deal of endurance and will be very easy to tip over. Your blade will then naturally gravitate towards the inner area of the stadium, and the slightest contact with RSMS should knock RSMS to the ground (sometimes even out of the stadium).

If your opponent shoots RSMS aggressively, dodging it becomes much more important-- and more difficult. It is imperative that you avoid contact with RSMS in the first few seconds of the battle, or your blade will just keep getting deflected and eventually KO'd.

Avoid using sliding and catapult shoot when pitting the above blades/combos against RSMS-- the last thing you want is to clash with RSMS head-on. The key to winning is to dodge and survive long enough for RSMS to lose some or most of its endurance.
