[GAMEPLAY] Mundo throwing invisible cleavers

Came across a game where Mundo is throwing invisible cleavers in a normal ARAM match, have not tried it o. People on the blue team could not see Mundo's cleaver nor it's path while it is airborne. When he throws it and when it lands, you can see the animation and hear the sound. Incredibly hard to dodge invisible cleavers. It occurred throughout the match, since no cleavers were seen other than in Mundo's hand.
