He has the best speed/acceleration combo out of all Super characters. But that's all (for now at least, because I can see his potential at high level).
I can't clearly hear the music because of the other sound effects but I hear only the I Am.. All Of Me. But the full version of his SFSB theme does have Live & Learn in it.
20k is more than enough to get cards for max level Special. At least if you don't want to rush and get those cards less than 10 days. But if you want to level him up as soon as possible...
I don't really know yet. When he just came out and I had him at level 1, I thought he's really bad. But he's definitely better at higher levels, even if he can't destroy badniks (- so I'm basically saying a level 1-7 Super Shadow is worse than level 8+).
another even though youre trash just collect some ring and easily beat the competition character, at least i dont hate him as much as i hate mephisto, ran against 3 of them one time, nearly threw my phone into a wall
