I'm not too sure if anyone has talked about this, but Shulk can true combo the first hit of Up-Air into Up-tilt. The first hit of Up-Air has set knock-back, so the Monado Arts don't effect its knock-back. HOWEVER if you have the Smash Art on, you can kill much earlier with the true combo. Sometimes when you hit the opponent with the first hit of Up-Air the opponent is sent behind you, but you can do a turn around Up-tilt or Perfect Pivot Up-Tilt to still connect the hits into a true combo. If you have the Buster Art currently active you can get some decent damage on an opponent. Another True Combo Kill Confirm is the first hit of Up-Air into Air Slash. Having the Smash Art on helps kill even earlier. Rage will also effect how early this true combo can kill. Hopefully this helps someone develop their smash game even further.
