MasterCard partnered with Riot Games and gaming lifestyle brand CLOAK to create a merchandise collection in celebration of the 2020 League of Legends World Championship. The collection went live on Oct. 31 at 5am CT with several items selling out in the following minutes.

Fans who didn’t get to acquire the cloak or the duffle bag can sign up for a waitlist, where they’ll be notified if these items come back into stock. The description says the offer is available until Nov. 6 as supplies last.

The long sleeve T-shirt and puzzle are still up for grabs, however. Those who want to benefit from this promotion can grab the items before they run out of inventory as well.

Mastercard introduced a “Thank the Fans” campaign for this year’s 10th anniversary of the World Championship. The campaign’s digital priceless experiences launched on the MasterCard site on Oct. 31 at 5am CT and will be available until 3pm CT. New experiences are unveiled hourly for 10 hours and are available for all players on a first-come, first-serve basis.

These opportunities varied from virtual meet-and-greets to tips, breakdowns, and world recap reviews with coaching staff or analysts.

“When Mastercard delivers experiences that people are passionate about, we see unequivocal joy and excitement among our consumers, and the passion League of Legends esports fans have for the game is undeniable,” said Raja Rajamannar, Mastercard’s chief marketing and communications officer. “I’m excited to celebrate the 10-year anniversary of the esport by thanking the fans, players, and shoutcasters by curating once-in-a-lifetime opportunities. This sport brings people of different backgrounds and ages from around the world together through a common interest—and that is priceless.”

The campaign’s digital priceless experiences will begin launching on Priceless.com on Oct. 31 at 5am CT. New experiences will be unveiled hourly for 10 hours and will be available on a first-come, first-serve basis. These “once-in-a-lifetime opportunities” will feature top streamers and shoutcasters, such as a Worlds recap with G2 Esports head coach GrabbZ and a shoutcaster workshop with Ender and Excoundrel.

Mastercard is simultaneously releasing a capsule collection on Priceless.com designed in partnership with Riot and CLOAK. The capsule includes a signature cloak, long-sleeve T-shirt, duffel bag, and puzzle—and the collection’s design was inspired by the overall League esports 10th anniversary “Take Over” campaign. Each item was sold for $10 a piece to commemorate the occasion.

While this campaign is over, Mastercard promised to be back with other campaigns in the near future as well.
