I did come up with a strategy after trying lots of different ones. I did "guns blazing" a few times(maybe 5% of my attempts) and tried other approaches after, I just didn't include the beginnings of them since it'd take up too much video time.

You said yourself "Be warned though, it's not for the faint of heart" and you were right. Anything involving a boss in a clown car is open for RNG based on the tiniest difference in mario's position as well as when he throws shells & when it shoots a fireball, so a proper strategy would always have an element of luck.

Didn't think you'd take it so personally, wasn't my intention to upset or offend you. My 3 levels have a total of 49 unique plays and only 17 stars so I'd honestly appreciate hearing from the 32 who didn't star it on why they didn't but I wouldn't go off on them if they gave their reason. Everyone has their own guidelines for why they do and don't star so I won't apologize for not starring based on my own guidelines. It's like comedy or art, it's subjective based on everyone's individual preferences.
