My faves...
-The Wave Change. Self created, published through the magicplazza. Very effective, visual colour change, done at spectators eye level.
-Erdnase change. Learn this from Erdnase, Expert at the card table, or puck up the annotated Erdnase for insights on this and the other moves from the original text from experienced and skilled magician and gambling experts.
I will say that I am currentky working on a variation on this which reduces the amount of cover used.
-Ego Change. Obviously, amazing. Daniel Garcia Projects are filled with good stuff, but the Ego change is up there with the REAL gems of the disc's. What I love most about it is it's versatility as a change, and as a generalised utility move.
-Side steal change. Looks very natural, I believe I learned this from watching a Jim Pace video some time ago. Looks very fair when done properly.
-Top Change. Just amazing. Such an underused tool, probably because people are scared of it, as it is an 'attitude' move- you gotta believe you can do it in order to do it right.
-Twirl Change and Shapeshifter. Very similar in appearance, one slow and the other very sudden. Both are amazing and effective.
