The worst of all time format

I am going to try to make a new format for burst and I wanted to ask the community for their input. For every season, what do you think where some of the least used in meta. I want to create a format where all parts used are parts that aren't very high on the list of strength. For example, DB drivers like High xtend+' and Bearing Dash won't be allowed, while drivers like kick and all might will. Just write what you think the worst parts of every season are in this forum, thank you.
What do you think about a format where you do that but you have to use duel and single layer era disks.
That probably could work, because most layers in db/bu are pretty meta. I just want to do all of them because I want to be able to see what people could come up with for all generations.
