Get off your high horse kid. I'd like to point out to you, as I have before on this forum, that because T11 sells custom cards this forum gets visited by many card collectors. One of which, a nice elderly lady who is an avid collector, lobbied a complaint about how difficult it was to ask serious card collecting questions on the E and T11 forums without someone retorting in a rude or inconsiderate manner. If you are a card carrying member of the Red Back Bike Nazi fan club then so be it. Interject your opinion when the topic is clearly pertaining to using custom cards in magic. In this case, the only thing we know is that the guy is a collector. There is absolutely nothing wrong with being an avid collector of cards.
I'll also add that a great many well regarded magicians are also avid card collectors. It makes sence, a great many hunters collect antique fire arms. The two go hand in hand. Trust me....you do not NEED red backed bikes....unless you are a gimmick monkey who needs access to the most gimmicked deck in human history.
Sorry for the rant. Truth is there are plenty of RBBNs who I hold in high regard. Perhaps the most compelling of which, Jamy Ian Swiss, would be happy to debate the use of custom cards in magic but would likely NEVER stoop so low as to tell someone who is obviously interested in collecting cards that he must buy a bike.(come to think of it he wouldn't stoop low enough to post on a forum lol.)
