It is legit, but gotta know the spacing for it. It Does %42, but i will go for 214, iceball, 224, slide for 41% instead for constant pressure. I wouldnt like to accidently drop my combo due to spacing or Input Bug. As to being new, It seems a variation of Jumping kick,d4 into iceclone (corner) but with 214 instead. Not sure, but it is a good combo.
