It really depends on what your looking for.
Distortion, Panic, TnR, and Digital Dissolve involve gimmicks.
Witness involves minimal set-up.
While all the Tricks on the Trilogy are basically impromptu but, you need to have pretty good skills with cards to pull it off. Just the basic moves really helmsey count, shapeshifter, dl's, but to make it look good they should be done smoothly.
There's loads of options for you but, definetely read the reviews. And if your going to buy something you should pick up a deck of guardians or 2. They are pretty good to be quite honest, the second edition I find are a lot better than the first. But before buying READ REVIEWS.
