I have trolled the enemy team multiple times by pretending to be a low hp ally and just sitting in lane a little bit, I have also as mid was backing happened to be around mid.... so I transformed myself into the mid laner since he was low and all the way near second tower to back (the enemy did not see this) and the enemy mid laner was low. So, when the enemy Zed came and shadow clone jumped at me there was a moment of "it was at this moment.... he knew.... he messed up." Before the enemy died. The enemy proceeded to tell me that was the first time that he had EVER seen that work.
Yet ive had it work multiple times :)
Though it seems to work best on tricking Assassins for some reason o.O
Also when you are support you can go relic shield and transform into melee champs.... you can hide your ulti for the cast time.... you can transform into a Caitlyn and out range mid or top laners even more.... the list goes on lol
