Problem is that when either clone uses a TP move the other one will aswell, meaning essentially double the TP moves and double the chance of getting terrored/death slashed.

Essentially if you have the numbers you should be able to take out 2 clones and win before PD wears. If you're lowmanning it like the video then you're riding your luck a lot more, if you pick the wrong one first time chances are you're going to wipe.
