Dr. Robotnik's Ring Racers - Phantom Cup (Master, Ruby)

Very easy cup on Master actually. Hardest parts are the non-tracks, even then there's much more difficult ones in both Prison Breaks and Sealed Stars. I actually got a near perfect run here only ruined by Gravtech lap bonuses.
Ruby was also made by Stapy-Paldea and has Gutbuster's statblock of 6 Weight and 3 Speed. Rivals seem a bit random though I guess as the creator hasn't made the other alliance members yet they're probably placeholders? Not 100% sure tbh.
