Shulk's knockback changes (150% Mario, all controlled for sweetspots (except maybe back slash)).
1.03->1.04
DSmash - 194->205 (up close)
FSmash - 215->223 (no tilt, up close, both hits)
USmash - 201-208 (both hits, Mario is already slightly above me)
<All Smashes are fully charged>
Ftilt - 136->134 (blade, up close)
Utilt - 115->122
Dtilt - 105->112 (about where the beam starts)
Bthrow - 104->104
Fthrow - 98->99
DThrow - 111->112
Uthrow - 83->83
Nair - 95->103 (used while practically inside Mario)
Fair - 102->110 (used very close to Mario)
Bair - 131->139 (where the blade ends and beam starts)
U-air - 131->139 (both hitboxes)
Dair - 117->124 (both hitboxes, no spike.)
Dair (Spike hitbox only) - 94->102
Back slash - no change in knockback from front
From the back 160->170? (I believe...? testing this from behind is difficult. Iffy.)
Air Slash (up-B) knockback - 137->138
Vision (counter) - Not going to attempt
Monado Arts - For later testing
Summary:
Most of Shulk's moves have an increase of 7 or 8. Notable differences:
-The throws are not at all or hardly at all changed in knockback.
-Ftilt has a slight knockback decrease
-Air-Slash is barely increased
I could use some help testing back slash's knockback from behind.
