I’ve decided to go for the Staff Ghosts in Mario Kart 8 Deluxe and started with Mario Kart Stadium. I used a couple recommended kart combos I found online and they didn’t help. What are some of the best kart combos that’ll destroy Staff Ghosts?
Whatever one you enjoy. It mostly comes down to player skill rather then there being a "best combination". If you're stuggling to beat them then best thing to do is practise the course so you're better at it, watch other players attempts and try to implement strategies they may be using, get good, etc.
