So I've been hitting training mode with Blanka, and testing stuff on the new characters, and man is Elena's hurtbox weird. With the increased pushback on crouching mk, now crossup mk, c. mk, s.lp, s.lp, h. ball only works on characters with a big hurtbox, and Elena for some reason. In fact, every combo, even character specific combo's I've tried work on her. Also, since we have some Elena players here, I'll warn you now before other Blanka's find out, even though you probably wont see it, but after a throw, Blanka has an ambiguous as fuck setup where j. hk can cross her up.
Also I found a setup for a mixup U1 after red focus. If you do j. hk, c.mk, s.lp, m. ball, RFC, and then land the mixup U1, you can do up to 816 damage :O
