I found it pretty hard to follow what was going on.. and perhaps too much was going on. The title does describe it well but I don't personally think that's such a good thing in this case. A card is selected, then 3 more, but what are they for.. then the original selection pops up in the middle, oh! ok.. but from then on I was totally lost. Where is the selection now? Oh, there it is, but why? etc. It feels like I'm trying to catch a fly, and it's not fun. Colour would help a bit to pick out which card is which, and maybe zoom in a bit, but overall I think there is just too much happening here. Is it a sandwich effect or some kind of hybrid? Patter would of course help as this routine has quite a few things happening; but if you're gonna keep it wordless I think simplifying it will help alot. The moves aren't bad at all; but as la0o9 said above, you need a better justification for some of them or they begin to look a little suspect. Overall an interesting piece but I do think it needs some diluting to keep it as fresh and interesting as possible. Keep at it!
