In the video I didn’t show it, but the alternative version I’ve shown can actually lead to 4 damage. That’s done by jumping back and following with jA fAxxjB.
Normal version works against: Grave, Jaina, Geiger, Argagarg, Setsuki, Valerie (forgot to show it, but it’s safe) and DeGrey (unsafe if he has Super).
Use alternative version against: Midori, Rook (unsafe against him), Lum and DeGrey (if he has Super).
