Cloak and Clone
Let
force-explode Shaco's clone. It's bad enough he has a blink and a cloak, but when he doesn't have buffs on him he's got a free target and skillshot shield.
It's supposed to be an illusion, yet unlike Leblanc's, it deals damage both with autos and on deletion. Red trinkets should make it disappear to allow counter-play.
Edit: Better yet, let's just take off the damage the ultimate does. At least then it doesn't turn any 1v1 in the jungle into a 2v1 he can blink out of anyway.
And in case any of you forgot what the range of that item is, it's nowhere near enough to catch the direction he's going in when he decides to blink away.
"Why should something disable someone's ultimate." You mean like making it required because any fight with him is 2v1 that he can easily escape because his blink is cloaked?
