Three sleights that immediately come to mind are the Bluff Pass, Marlo Tilt, and Top Card Cover Pass.
The Bluff Pass is probably my favourite of the three. I would recommend Joshua Jay's excellent video teaching his handlings on his website Vanishing Inc. Aaron Fisher also has a well constructed Bluff Pass in his book The Paper Engine.
The Marlo Tilt is probably the most commonly known move - but funnily enough, I can't actually think of where it is taught, except to say it's (obviously) in some Marlo book, and in many places that teach versions of the ACR - 5X5 Japan from Richard Kaufman is one example, in what is I seem to recall the only ungimmicked effect in the book (might be wrong, been a while).
The Top Card Cover Pass is the hardest of these sleights... I remember topics about where to learn this popping up - but I don't remember the answers. If you do a forum search in the Card Magic forum, I'm sure you'll find something.
Hope this helps!
