deft ivy
You use it and get a tad speed boost before slowing down hitting walls slow you down more but you bounce off
Could be used with some sort of wall track you can bounce off of it just re uses minevart tracks
Does damage when jumping
And has a spinner switch that you have to use the spinner to ride in it and spin the switch in order for it to activate
Maybe the switch could have 4 shape outputs too and if it has a shape intake can lock in and out
