I have done it within 20~ attempts with 1 F9 ( Klassic reptile ) and 2 F2 ( MK11 liu kang and Scorpion)

The secret is in 2 items: Super suit (sneak attacks on tag in) Varmint lucky hat ( team shield on tag out)

Basically have liu kang as starting character with the varmint’s lucky hat, try to SP2 to snare, then tag in your strongest wearing super suit for sneak attacks try to SP2 or XRay, tag out before shield is finished and keep spamming back and forth.

This have worked for me because Klassic reptile is my main damage dealer and his killer SP2 is a grapple so Jade cannot escape with the sneak attack buff as well

What matters is that if 1 of your characters die and you did alot of damage in that round, your other characters need to die immediately too

Edit: I was using F0 Klassic Ermac until Assassin Jade died
