Universal, deals a little less damage on Big Band but still works fine.
On corner, change the first 9 for an 8 for it to work.
The first 2MK can be exchanged for a 5MK for a little extra damage but using 2MK guarantees better consistency and it flows better input wise.
This is my first notation, but the start of the combo is Beo using his Taunt, and then use valentine's assist at the same time(in the video, it's the second assist), and the 5 MP in the combo's end is only mic drop, so don't hold too much the button.
