Know where Seahawks linebacker Cassius Marsh’s ‘Magic’ cards are?

Seahawks linebacker Cassius Marsh needs your help in finding one of his most prized possessions: his “Magic: The Gathering” cards.

Marsh took to Twitter, asking followers to help find the stolen cards.

Marsh told the Seattle Times that his girlfriend went to a nightclub in downtown Seattle on Tuesday night, where his car window was smashed and two backpacks were stolen from the backseat. One backpack had a team-issued iPad, the other had the cards. The cards are estimated to be valued around $20,000 to $25,000.

 “Magic: The Gathering” is a popular trading card game, and Marsh has been playing it for years and it helps him relax.

“I’m a nerd, for sure,” Marsh told the Seattle Times. “I’ve been playing since I was 11. How people like gaming, I like cards.

“It’s not even the money. I really enjoy playing the game. To me, that’s what I do to get my mind off things sometimes. You know how people zone out sometimes? That’s how I zone out. It’s hurtful because those are one things I really care about.”

He is offering two tickets to the next Seahawks home game to whoever finds the cards.

In the meantime, Wizards of the Coast, publisher of the trading card game, sent Marsh a care package while the search is on.
