House of Cards House of Cards The House of Cards was the headquarters of the Royal Flush Gang. It resembled playing cards. The exterior of the house was on Earth, while the interior was Apokolips, thanks to Stargate technology, which created a dimensional-warp. The house was destroyed by Firestorm, and presumably not rebuilt. References ↑ As seen in The Wild Cards.
