Did you do 15 matches in a row while on endless? I believe that's what got me it, so not sure why you didn't get it then.

Don't remember if I had gotten the normal revenant one, but I know I unlocked the Dark Emperor Liu Kang skin by doing what you said about the challenge towers. Basically, you have to have a friend or someone beat a challenge tower, and then send you a challenge to beat their score on it. Beat a tower challenge someone sends you eight or so times and you should have it.
