I know how it works now... not sure if it's a cheat He just uses the fear of catas to fear his own mumas. But I guess it can be unbalanced if Mordor is allowed to do so. On the other hand it would make the usage of Mumas more attractiv.
I think we could allow it because it does not walk over units it only chases them, if you want to trample then trick is off again
I don't think it wll change a great deal of how games are won but might make things a bit more fun
