This is a visual routine that really is easy to perform. You can probably have this running smoothly in about 15 minutes if you have some minor card background. There are pros and cons to the gimmicks. The pros are that you can make them from any deck you like to use, and construction of them is obvious so you'll be ready to make your own in a few seconds after seeing these.

Unfortunately, the gimmicks would have been so much better if they had been specially printed rather than created with existing cards. They are very easy to spot without really careful handling and audience management because when the cards are face up there is something obvious going on you can notice. Again, this could have easily been avoided by simply having the cards printed instead of crafted, though you can craft these out of any deck you use so there are advantages.

If you have any experience with card-splitting you'll be able to make much better gimmicks than the ones included. In my opinion, this isn't the best ace assembly out there, but it's probably one of the easier ones.
