While an excellent deal for its price, I'd just like to note that a significant portion of these Challenger decks is going to rotate out of Standard in a couple of months.
Currently $7 less than Amazon ($86) and $3 less than eBay ($82). If you're patient and OK with an additional week or two shipping, or if you're unhappy with eBay, this is probably worth picking up.
the packaging was quite awful to say the least... I don't who had the bright idea to shove these things into a undersized thin bag... the things came looking like they went through a damn war.
