]Alright, so I decided to try and uncover all the Monado symbols that appear in the video. Looks like Shulk is becoming much more unique then we realized.
I've tried to screenshot the best images of each art symbol that I could and this is the result.
First one is most definitely Monado Speed and later on in the video, you can see the kanji appear and fade away quickly in the white circle, indicating that the buff timer is over.
The rest are a bit of a guess so here goes.
I went with Monado Purge for the second one. The symbols looks pretty much the same and the symbol is green in Smash, just the way it appears in Xenoblade.
Now I think I've found Monado Buster. This resembled Monado Buster or Monado Shield, but I went with Moando Buster as I think it looked closer to the same kanji character Monado Buster had.
The last one, I went with Shield. It doesn't look similar to any of the kanji on the other Monado arts so I inevitably went with Monado Shield. If we were to go by color, this could also be Monado Armor.
There's another moment later in the video where I believe Shulk switches to Monado Enchant but I can't seem to grab a good screenshot. The only lead I have on that is that Shulk's hands start to glow red.
