Houston — The party game Cards Against Humanity says it's bought U.S.-Mexico border land and hired a lawyer to try to stop President Donald Trump's proposed border wall.

A promotion called "Cards Against Humanity Saves America" offered 150 000 subscribers to its game a map of the land and a "certificate of our promise to fight the wall."

"There’s no time for questions—now is the time to act. You give us $15 (about R215), and we’ll send six America-saving surprises right to your doorstep. It will be fun, it will be weird, and if you voted for Trump, you might want to sit this one out.” said the website launched by Cards Against Humanity.

Cards Against Humanity said that contributing to the land purchase was the first of six days of 'surprises' that customers would be receiving in December.

To build sections of the existing border fence, the US government took hundreds of private landowners in Texas to court. A wall will likely require new lawsuits.

But stopping new construction through filing lawsuits would be difficult. In many cases with the fence, the U.S. government started construction even as fights continued over how much it had to reimburse landowners.

A message sent to the company was not returned Wednesday.
