It's not suppose to be a magical blink. It's him moving so quick he disappears. It's like Road Runner. He leaves behind a dust cloud. Imagine Super Teemo... when he activates Can't Catch Me you here the *puoof* sound and he leaves behind a Teemo shaped cloud that then dissipates. I never imagined it as a magic trick, only the Swift Scout showing off how Swift he really is.

P.S. The change to his passive was in light of the new blink ability, since it Camouflage's him. It means he can now "activate" his passive. Cast W for 40% attack speed and some movement speed.
