I'm all for this mov lol it was cool, original and no different then Sektor's seeker in UMK3 or an unblockable move or Sheevas teleport stomp. Just move lol...
Anywho, I hope the other Sub-Zero has this move and the ice teleport and the clone or shower again. Since the original has the ground ice, freeze ball and slide. I think good Sub has to have ice teleport, ice nugget, ice blast and either Ice Shower, Ice Clone or the self freeze.
