Well, this is my first major post here, so hopefully, I don't screw this up. (Just keep in mind that I'm called UnoptimallyNiko for a reason).
Pretty much what I'm covering is some easier versions of literally everything that there is on the wall, and then amping it up to the max.
Literally the only Universal Combo I have here with all characters getting the same damage.. somewhat:
6[A] sf.A (W!) 5X
The damage on this varies from the distance you perform the 6[A]
sf.A from, this applies to the other 6[A] combo here as well. 188 is from the furthest distance away, 244 being the closest distance.
This next part is split into Two Parts, whether there's a cross or not in the Combos. By cross, I just mean if the character is against the wall or not after the 2[X]. Non-Cross meaning they're still on the wall and Cross meaning they're on the other side and don't get Wallsplat damage when the combo is over
jA (one hit)
Main: jA (W!) 2[X] jY jY jY = 232 (Non-Cross) & 202 (Cross) // Non-Cross Only: jA (W!) 2[X] jY jA 4A~B~R jY = 243
Pokemon That Cross*: Chandelure, Empoleon, Aegislash, Shadow Mewtwo, Braixen, Gardevoir, Machamp, Charizard, Decidueye, Lucario, Gengar, Suicune, Blaziken, Mewtwo, and Darkrai
Pokemon That Don't Cross*: Scizor, Aegislash, Garchomp, Pikachu Libre, Weavile, Pikachu, Sceptile, and Croagunk
jA (two hits)
Main: jA (W!) 2[X] jY jY jY = 280 (Non-Cross) & 250 (Cross) // Non-Cross Only: jA (W!) 2[X] jY 4A~B = 282
Pokemon That Cross*: Blastoise, Aegislash, Shadow Mewtwo, Gardevoir, Machamp, Charizard, Lucario, Gengar, Suicune, Chandelure
Pokemon That Don't Cross*: Blastoise, Aegislash, Scizor, Garchomp, Mewtwo
Some pokemon can be Non-Cross and cross, but be careful, because you can accidentally move them away from the wall, such as Blastoise and Aegislash.
(* Pokemon not on the list just can't be hit at all by select terms)
For both jA combos, you can replace any jY after the first with jA to get a hard knockdown.
Main: 6[A] sf.A (W!) 2[X] jY jY = (Max Damage Only): 264 (Non-Cross) & 234 (Cross) // Non-Cross Only: 6[A] sf.A (W!) 2[X] jY jA 4A = 272
Pokemon That Cross: Blastoise, Garchomp, Braixen, Suicune, Shadow Mewtwo, Pikachu Libre, Gardevoir, Charizard, Pikachu, Gengar, Lucario, Chandelure, Sceptile, Empoleon, Mewtwo, Croagunk, Darkrai
Pokemon That Don't Cross: Aegislash & Weavile
Pokemon That This Doesn't Work On: Scizor, Machamp, Decidueye, and Blaziken
6A Combo Damages from above
Main: 6[A] sf.A (W!) 2[X] jY jY // Alternate (Hard Knockdown w/ Cross Only OR W! with Non-Cross): 6[A] sf.A (W!) 2[X] jY jA
Cross Damages: 234, 210, 198, 186 // Alternate Damages: 235, 207, 193, 179
