I keep seeing people that seem unaware of the Clan Mechanics summary below the fold on the Product Page here, but in summary, it's below:
QuoteCrab: As rugged, stoic, and tenacious defenders of the Empire, the Crab are at their best when they are defending against attacks and reacting to an opponent’s aggression, weathering your opponent’s best attacks, and retaliating when your foe is most vulnerable. As builders who excel at living off the land, holdings are important to the Crab to protect their provinces and power their characters.
Crane: The Crane are known throughout the Emerald Empire as a political powerhouse, with wise and honorable courtiers guiding the clan and protecting themselves from external threats. In the game, you must leverage this political might to devastate your opponents during conflicts, keeping your characters honored to increase their skill and controlling the board by pushing your opponent’s characters away.
Dragon: The Dragon are a mysterious and individualistic clan. The use of attachments is one of this clan’s greatest strengths, and it’s wise to invest in a few powerful characters with plans to give them multiple attachments. The concept of balance is also important to this clan, and they are well suited for both military and political conflicts. You must take advantage of this flexibility and strike wherever you opponent leaves an opening.
Lion: The Lion are a proud, aggressive, and violent clan that leverages its strong military skill to win conflicts. Lion decks frequently aim to swarm the play area with characters, strengthening their presence through numbers. However, Lion characters with political skill are harder to come by, so it’s important to have some extra fate to keep your few courtiers and politicians in play.
Phoenix: The Phoenix are the masters of magic in Rokugan, but they are also staunch pacifists with little interest in warfare. Wise players will use the clan’s shugenja to trigger powerful effects against your opponent from the safety of your home area. The clan’s mastery of the elemental rings will also help to deny your opponent the effects they aim to use against you while ensuring you can use the rings you need to win. This clan’s distaste for violence can also be used as a calming influence upon your opponent, making overt aggression and military conflicts much less effective against you.
Scorpion: While playing the Scorpion Clan, you’ll want to make high honor bids in order to draw extra cards and surprise your opponents with potent tricks and traps. Yet you must always maintain your deepest loyalty, lest you lose all honor and the game. Dishonor is also a powerful tool when turned against your foes to keep their skill low and their hopes of beating you in conflict even lower.
Unicorn: The Unicorn are an aggressive, practical, and nomadic clan that has mastered the arts of mobility and warfare. You must use the clan’s powerful cavalry characters to outmaneuver your opponent during conflicts, brining your characters into and out of conflict to keep your opponent on edge. The Unicorn are strongest when they are first to act, and much more comfortable attacking than defending, so be sure to play aggressively and get to your opponent before they get to you.
I found this quite useful as I'm new to the L5R universe and am still debating which clan I want to be my main clan. Hope it's useful to others who may not have noticed it.
