The suspect smashed the bottom glass of the front door of The Comic Hunter, climbed through the hole, and then went straight for the display case containing the "Magic" cards. His movements were caught on the store's security cameras.

The thief made off with an undisclosed number of cards, including, CTV News reports, a "few" rare Black Lotus cards, valued at about $6,300 each.

The theft of "Magic" cards has become increasingly common, leading some store owners to require anyone wishing to sell them to provide photo I.D. The cards are relatively easy to dispose of -- some of them are incredibly valuable -- and they're difficult to track once they become  part of somebody's collection. In January, two men broke into a gaming store in Austin, Texas, and made off with $75,000 worth of cards, while in August $1,300 worth of cards were taken from a store in Iowa.

"There's a huge global market online," Jonathan Armstrong, manager of The Comic Hunter, told CTV. "Basically, where you can buy and sell anything online, legal or illegal, there's a market for cards too."

The Black Lotus cards are particularly valuable, with one pristine Alpha Black Lotus listed for as much as $100,000 in 2014.
