The creators of adult game Cards Against Humanity have purchased a vacant plot along America's southern border, in the hopes of preventing the controversial wall the country's president Donald Trump is planning to build.

The team made the purchase, and hired a lawyer that specialises in preventing the state from taking private land for public use, as part of a holiday promotion called Cards Against Humanity Saves America.

"It's 2017, and the government is being run by a toilet," said a statement on a website created for the initiative. "We have no choice: Cards Against Humanity is going to save America."

Trump's plans for a wall along America's southern border have proved divisive since he proposed them during his presidential campaign, and seem to be moving forward since portions of eight proposed designs were erected near San Diego last month.

"Donald Trump is a preposterous golem who is afraid of Mexicans," the group said. "He is so afraid that he wants to build a 20-billion-dollar wall that everyone knows will accomplish nothing."

"So we've purchased a plot of vacant land on the border and retained a law firm specialising in eminent domain to make it as time-consuming and expensive as possible for the wall to get built," they added.

Cards Against Humanity, which brands itself as "a party game for horrible people", is played by filling in sentence blanks on one set of cards with words or phrases from another deck. The aim is for the outcome to be as funny, disgusting or politically incorrect as possible.

As part of its holiday promotion, buyers of the game will be sent six "America-saving" gifts in exchange for $15 (£11) during December 2017.

Participants will receive an illustrated map of the land purchased, a certificate outlining the promise to fight the wall, a few new cards and other surprises. The offer was sold out at time of writing.

Trump's wall has triggered a host of responses from architects and designers – some serious and others less so. Satirical suggestions include a spoof of an IKEA flat-pack furniture kit that offers the president a cheap construction option and a 1,954-mile-long dinner table in place of a barrier.
