My most active characters I use online is Waluigi Rosalina, Wario and Daisy. But as for baby Rosalina I only use her mostly on time trials on 200cc.

Everybody has an opinion of their favorite combo in Mario 8 deluxe I'll explain my reason why I like my type of combos in Mario 8 deluxe.

For vs race online

My first favorite is Waluigi wild wiggler because so far he has good speed, acceleration and good invisibility witch is why I use him for most courses. But not only I use him in online but I do use him in time trails in 150cc which I find them really good for speed and mini Turbo.

My second favorite is Rosalina Teddy buggy because so far she has good acceleration, handling and traction which is why I mostly use her for sharper turns in some course. But not only I use her for online but I do use her on time trials in 150cc which I find her really good for sharper turns

My third favorite is Wario landship becausebecause so far he as good speed, acceleration and traction but so far I don't really use him for most courses but I do use him for underwater courses and I mostly use him for battle mode. Not only I use him in online vs race and battle mode but I do use him in time trial in 200cc since he has very good speed two against some ghost that are too difficult to catch up.

My fourth favorite is Daisy linkstriker because so far she has a good acceleration, handling and traction but I don't use her in 150cc or under due to her speed being slow but so far in my opinion she is good on 200cc witch is why I use her only on 200cc

My fifth favorite is baby Rosalina biddybuggy because because so far she has great acceleration and handling but good traction but her weight and speed is not great in online which is why I only use her on time trials witch she's great on 200cc in my opinion
