BLANKA: SHOUT OF THE EARTH(ANTI-GROUND) ULTRA COMBO
I'm currently playing Blanka's Trial, and it's asking me to use the Ultra Combo: "Shout of the Earth(anti-ground), But every time I try to use it, I don't hit anything. Even when I'm right next to my opponent!(NOTE: I use the Touch Screen when using my Special skills)
How exactly does BLANKA'S Shout of the Earth(Anti Ground) Ultra Combo work?
