Masked Shaco
When you Q with shaco in that skin you can see it clearly from a bush even when its not warded (the puff of smoke) ,and the other skins for him does not change his Q visibility.

All skins and classic leave the puff of smoke for enemies, even when not warded. It's supposed to be the tiny bit of counterplay to the ability in the fact that you can happen to see it and react since "Buy a pink" can't always be applied.
