The hands on mine go on and come off pretty easily. Not bad easy, though his hand does struggle to support the weight of the largest card effect. He does have the extra post for it though so it's clearly something Medicom acknowledges.
I will say, the coat looked more red in pictures than I personally liked, but in-hand it's not as intense. I do have to chuckle at how the box labels this "Comic Version" while the image from the comic in the upper right hand corner has that more light brown colored coat of the original release. I can certainly see why some who have both versions would swap coats.
