Soooo, just something interesting.......utilt can jab reset but only the first hit and the way to get that first hit is by doing a sliding utilt either by sliding pivots from a jump or turnaround dash, a perfect pivot or even simply walking utilt under a platform and yes it jab resets at kill percents (only issue is the spacing is really strict). I wonder if Smashville's platforms will be of use...
You can also use the first hit of utilt to drag people off platforms e.g battliefield, if someone is near the edge you can do a sliding utilt to drag them off sending them into the special tumble animation that cant be teched and therefore you can follow up with another reset or at kill percents, Fsmash.
Situational I guess but it gives us another use for utilt and utilt is great at pressuring under platforms anyway with its low cooldown so no reason not to go for it.
