Just labbed it, viable tech
I don't know how viable that is, but the fact that red orb destroys ice clone and it has fast recovery which allows Liu Kang move alongside with red orb might be a sign of a better match up vs Grandmaster. Thoughts?
You can also put a red orb in front of yourself, then throw another one towards ice clone and run with it. Putting one red orbs in front of yourself might prevent Sub-Zero of trying to go towards or it might force him to use EX slide, which can be baited, blocked and full combo punished.
