Damn, yeah noticed it too as i went through the animation editor, i'll still mess around with missing ones or some abysmal looking old ones like solarbeam, considering i've been porting some gen8 moves that use existing mechanics i'll put that elbow grease there. Checking the work that's been done for Z-moves really impressed me, guess with some creative movement and positioning one can simulate these dynamic 3d effects.
Just wish there was a CTRL+F in that animator editor in debug, half the time i'm scrolling up and down to check if there's a needle arm animation i can tweak for grass knot.
