It's not a collection without at least 1 Tenyo item. Dicer, none of those decks are rare. Maybe in 10 years some of them will be considered rare and sought after but not now.
Overall I think this highlights what magic has become to the younger generation.
Understanding why you receive negative feedback is more important than accepting positive feedback.
On the flipside, to everyone who posted that he now needs to learn the tricks, the description of the video says he's had the collection for two years. I doubt he just bought it all but didn't learn any of the material in two years. That seems like a huge waste of money. Not saying he should keep buying, just saying don't immediately jump to the worst conclusion.
