The only reason I asked is because I had seen reviews on other sites claiming that the effect is actually far from easy, requires serious sleight of hand, and so on. I'm not trying to call anyone out or anything. I just, naturally, want to be 100% sure I'm not going to have to jump through a ton of hoops. T11 has never let me down, and if it's true that I can perform at least some version of the effect in the trailer (matching cubes and quick solving behind the back) with some ease and practice, this will go straight on the holiday wishlist.
