That One Won't Take Too Long, I'm Close To Getting That One Legitimately.
Jade Turns Pink/Blue Just Like Reptile Turns Orange, Blue, Red, And Grey When You Fight Him, It Just Happens Mostly After Reptile's Special Moves.
Best Thing I Can Suggest Is Play Through The Arcade Tag Ladder With Two Characters That You Want To Master ; And Play On Expert ALWAYS.
I Usually Get Double Flawless(s) On Expert Up Until Challenge 4, The AI Then Starts Mixing-Up, And Punishing Against Every Attack.

You Probably Get More Time For Playing Offline On Average Than You Do Online, For One ; Less Loading Time, More Fighting, And Less Waiting To Get An Opponent That Drops Out Near-End Of The Match.
