I don't know how but my decks seem to last me ages compared to what I read on forums and so on. I have had opened decks of various brands, tallys, bikes, dnd cards and others and they've been opened and used for 1, 2 or even 3 years, now I dont use them everyday but I've never had a deck that cant be used for something, I very very rarely throw any decks away and so what about you? I just read one comment on facebook, it said ''lucky i got 4 bricks...
that should be enough for 5 months?'' He was talking about the v6's, not sure if he's joking but even if he is I see this kind of thing alot, if your performing then maybe it would be the case but it's suprsing people get through so many.
