Help with triggers?

No one at the battle.net forums was able to answer this...

I am creating a hero arena (yes, I know its unoriginal, but at least it's high quality!) in which Mass Teleport features prominently. I want to make it so that in duels, any hero that happens to have mass teleport will not be able to use it. Evidently there is no way to alter the Mass Teleport functionality. I tried using the trigger "Unit recieves an order targeting an object" and "point" with the condition being order = Mass Teleport, but it didn't register. What am I doing wrong? Is what I am trying to do impossible?

Thanks a lot!

You cannot make a skill that a hero owns but when he tries to use it it does not work. Just change the units hero ability if you don't want him to use it.
(Incase you didnt know thats in the unit editor :foot:

Try using the Player - Enable/Disable Ability action.
