I grew up in a card playing family. We enjoyed Whist, Gin Rummy, Bridge and many other games but the perennial favourite was the traditionally Irish game of Twenty Five. Twenty five is a trick taking game like bridge or whist but the ranking of the cards is quite bizarre, it goes like this:
Trump Cards (Trump suit is selected by turn of card at the start of each round)
5 of Trumps
Jack of Trumps (more generally called the Knave)
Ace of Hearts
Ace of Trumps (bonus of allowing the holder to "rob" the card turned over to indicated trumps)
King of Trumps
Queen of Trumps
The remaining trumps in natural order (10,9, 8 ...) for red suits or in reverse order (2, 3, 4 ...) for black suits. ("Highest in red, Lowest in black).
Non Trump Suits
The remaining cards natural order (10,9, 8 ...) for red suits or in reverse order (A, 2, 3, 4 ...) for black suits. ("Highest in red, Lowest in black"). The Ace of diamonds is therefore worthless unless diamonds are trumps and is often referred to as the worst card in the pack.
Joker In some parts of Ireland one joker is added to the pack and it counts as the highest trump card outranking even the five of trumps. Most players however refuse to play with the joker believing that it signifies the devil and will bring bad luck.
Twenty five is a very enjoyable fast paced game that combines skill and luck and makes a great party game. You can get a more complete explanation of the rules here.
Why am I giving such a long explanation of a complicated card game I mastered in my youth? Well ... it's because I feel a strong need for personal affirmation after discovering that I can't make head nor tail of the trading card game built into Free Realms? Are all these trading card games so complicated with similarly arbitrary rules?
I really like the demolition derby though.
