Is this SERIOUS? This can't be serious. Or he must be a total nutjob.
Anyway, back in the REAL world, he does have a few morsels of useful advice: color is a huge impact, quality paper gives quality impressions, even a touch of die-cut specialization can add something great to a card. The size is just an inconvenient bugger, the die-cut makes it impractical and prone to getting beat-up, the third fold is totally gratuitous, and obviously the pop-up takes it home into "satire" country (I seriously loled when it popped up)... but any one of those ideas, even the tacky cheesy foil, could be OK, in the right application. A few of them make a hot mess, and all of them make a viral internet cewebrity.
I was thinking of doing a square card and/or rounded corners on my next card, and maybe a spot varnish for the actual logo so as to make it more minimal since a non-standard size and rounded corners (and a vibrant color on one side) could be a lot, visually. Or maybe embossing it, though I bet that's expensive.
