Josh was great at the store. Got an easy deal done with no issues. Good store that just opened a few weeks ago and a good shop to go to in the Denver area

★★★★★ Jonah, May 2021

Hello, my name is Jason and recently I had family visiting me from another state. My nephew is a huge magic the gathering fan so we decided to check out this card shop.

★★★★★ Jason, Aug 2026

Highly recommend this family owned card shop! Good prices, nice selection, and friendly/knowledgeable employees. They spent a good bit of time answering my questions about grading cards and the hobby in general. I spoke with Emma & Nick for a while and gained a lot of good information from them.

★★★★★ Greg, Nov 2025

Was there recently and I went to get some small pokemon singles, most of them were below actual value of asking price and there were small amounts that was actually worth it. Like the 3 dollar singles were maybe 1.76 dollars instead and that’s for mint condition, these cards are lightly played+.
