I thought that the 3rd image is about Game of Thrones. But I guess I was wrong. The idea is that King of the Hearts is about the Starks (kings of the North), the King of the Clubs are Lannisters (kings of the South). The dogs are Lannisters' helpers, the treacherous Freys and the Boltons. And the Jack of the Clubs is about the Ironborn who warred against Starts (swords) and offered the fleet to Lannisters (the ship).

The weakest place of my assumption is that the Lannisters could be better represented by the Queen, not the King... .. So... :(
