  Seriously one of the best card shops around. The owners are cool, down-to-earth guys who actually take the time to talk with you and make it fun. No pressure, just good vibes and a real love for the hobby. Awesome selection of new releases and older stuff, too. Easy place to spend way more time than you planned. Definitely worth a visit.
