Justice:

Who else but Athena for our Justice card?  Not only was she the goddess of justice, but she presided over one of the most famous court cases in Greek mythology.  It started with Agamemnon, king of Mycenae, who needed a favorable wind to get his battle fleet to Troy.  Paris, the prince of Troy, spouting some drivel about Aphrodite and a golden apple, had run off with Helen, the beautiful wife of Agamemnon’s brother.  Said brother happened to be the king of Sparta, where looking at someone the wrong way was considered an invitation to a duel.  Kidnapping the king’s wife, well, that was an outright act of war.

War made the Spartans very happy, since it was pretty much the national pasttime anyway, and Agamemnon wasn’t exactly adverse to it, considering that his state was basically a cover for a bunch of pirates.  They’d already sacked half the countries surrounding the Aegean, and had probably been eyeing wealthy Troy even before Paris gave them the perfect excuse for a raid.  The only hitch was that the wind was blowing against their ships, keeping them stuck in port instead of off pillaging.  Not being the patient sort, Agamemnon made the decision to sacrifice his daughter to the gods in return for a favorable wind.  The war was a point of honor, and Agamemnon assumed that his wife would be down with whatever he had to do to restore the family’s good name. 

Clytemnestra, the wife in question, had a slightly different view.  She bided her time, and when Agamemnon returned covered in glory, she went after the old man with an ax.  Agamemnon’s victory celebration had to be quickly turned into a funeral.  Nobody protested this too much at the time; the war had lasted a decade, giving everybody in Mycenae time to notice how nice things were with Agamemnon gone.  That was especially true of Aegisthus, the queen’s lover, who afterwards made a habit of getting drunk and dancing on the dead king’s grave, talking smack about him and his children.  Predictably (because this was a Greek legend, and they loved them some drama) one of those children, Orestes, grew up to kill his mother for murdering his father.  At which point the Furies got involved, striking Orestes with madness for matricide. 

Athena finally decided that enough was enough and convened a court in Athens to decide Orestes' fate.  But when the final vote was tallied, it was a deadlock: six to six.  That gave Athena the deciding vote, and she opted for acquittal.  At first glance, her vote might seem a little odd.  Orestes had, after all, killed his mother.  Shouldn’t he have been punished for that?  A modern court would say yes, but Athena was judging based on the bigger picture.  The cycle of vengeance had to stop somewhere, or more pain and suffering were sure to follow.  Her ruling might not have been fair where Orestes was concerned, but it prevented many more acts of violence from being perpetrated (against his sister Electra, for example, who many blamed for egging him on).  It preserved the peace by ending a bitter feud, and was therefore the only just ruling for all those people who had yet to be drawn in and whose lives had yet to be ruined. 

Justice reversed:

The gods had started bickering over the number of worshippers each of them had.  Many cities had temples to multiple gods, and it was getting so that someone might sacrifice to Hera in the morning, and then slip off to slide a little something Aphrodite’s way that afternoon.  Basically, the gods were feeling used and a little dirty, not to mention unappreciated by those damn humans. Something had to be done.

The decision was finally reached to give important cities (aka those with many worshippers up for grabs) patron deities who would get the lion’s share of devotion from the local population.  A large city in Attica drew the attention of both Athena and Poseidon, and neither one was above a little bribery to swing things their way.  Poseidon showed up first and, with a totally unnecessary amount of fanfare, caused a spring to bubble up in the city.  Too bad it was salt water which, while pretty, wasn’t of much use in an arid environment.  Athena ignored Poseidon’s prior claim and staked her own by giving the city a much more useful commodity: the olive.  She planted the first olive tree, thereby snaring the devotion of the population, who gratefully named their city after her.  Athens became known around the Aegean for the fine quality of its olive oil, which made it a fortune and helped it to found an empire.
