I mean, pretty much this.the bad side of having auto jump-cancel Ness/Yoshi is that after the aerial you're still Ness or Yoshi, and Peach is Peach with Falco's laser.
However, I feel like Ness would be better off here than yoshi because even though yoshi has some nasty aerials, ness at least still has some recovery option. Also, Uair chains are a nightmare.
