Althrough I'm a freshman in Cardistry/Card Magic, I already buy decks like crazy, I just have a huge collector heart, you know . But I'm a little hesitant when it comes to buy sold-out decks (on shops other than T11 or eBay), I'm just afraid of counterfeits. Are the stakes high to get fakes sold or can I chill? Of course I check from where the decks come (i.e. I would never buy from Asia) and it's not super mega rare cards I'm currently looking for (i.e. I just checked eBay for D&D Smoke & Mirros V5 and found some from UK)... Any advice?
