Cards Against Humanity has become the go-to party game in recent years. With countless expansion packs and hilarious stunts — like last year’s $100,000 “bleak hole” — this year, the company has combined a holiday stunt promotion with a way to disrupt President Trump’s plans to build a US-Mexico border wall.

The game company has launched “Cards Against Humanity Saves America.” For $15, buyers will receive what the company’s website describes as “six surprises in December” while also donating to the company’s recent purchase of a plot of land along the US-Mexico border. The company’s stated goal in purchasing this large patch of land is to bog down the President’s attempts at building a border wall by making the project “as time-consuming and expensive as possible.”

Each $15 contribution will be used to help compensate for the land purchase; portions of each purchase will also be put toward Cards Against Humanity’s legal fund. As for exactly what buyers’ “six surprises” will be, Cards Against Humanity has dropped a few hints.

“On Day 1, all Cards Against Humanity Saves America recipients will get an illustrated map of the land, a certificate of our promise to fight the wall, some new cards, and a few other surprises,” they said on their website.

While we don’t know exactly *where* the plot of land is, hopefully, all will be revealed in the coming days. The mystery seems to be part of the appeal: Since launching late on Tuesday, Cards Against Humanity Saves America has already sold out.

Besides the 2016 bleak hole stunt, Cards Against Humanity’s recent promotional campaigns have included 2014’s “Bullsh*it” pack, which involved the sale of actual you-know-what from actual bulls, and 2015’s “Buy Nothing,” campaign, where the company successfully sold “nothing” to fans. The 2014 promotion donated the gimmick’s proceeds to an organization called Heifer International, a charity that buys cows and other farming equipment for people living in dire need around the world.
