About the Ellusionist decks:
I believe that the Ellusionist decks are made from a thicker stock and, from what I have heard, are harder to handle. Makes a bit more sense to me as Ellusionist is virtually an all magic website.
The video:
Oi vey, the video is just making fun of cardistry. To an extent, it's ignorant, but it DOES touch on (albeit a very shallow explanation) of what is wrong with cardistry.
I'll delve into it further.
Last year, CaseyRudd pointed out that cardistry has plateaued. This is why cardistry is getting made fun of. Nothing interesting or innovative has come out that has really rocked or changed the cardistry community in a few years. The CLOSEST thing to something different being done was the winner of the Magic + Cardistry contest last year. It DID do something different than all the other entries that year. That's why it won.
The thing that lacks in cardistry, which the video points out, is 'headless torsos playing crazy music and doing elaborate flourishes.' I can't exactly say the video is wrong there because, even as a newbie to cardistry, that's what MOST cardistry videos look like.
To further that, there is no plot, no story, no message, and no meaning to virtually every cardistry routine. It's really just elaborate flourishes and display of dexterity.
While I agree that flourishing, to an extent, is best utilized in magic routines because of the lack of plot or meaning; that doesn't mean that cardistry can't be improved upon as a whole.
CaseyRudd has said that there is a lack in personalization in cardistry.
I have a couple ideas and one of them is that cardistry needs to slow down. I think, on a very ignorant level, cardistry (currently) is about doing 60 flourishes a minute. There's a lot of great ideas and talent out there with incredible dexterity and speed; but I think it needs to slow down to start going in a different direction; a more graceful presentation.
