I got into L5R in...Ivory. Yeah, it wasn't a great time.
I have a ton invested in Magic: The Gathering so I'd rather get into an LCG than another CCG. The biggest draw of L5R for me has been the stories that grow around narrative prizes, clan loyalty, community, and so forth. It's a completely different incentive from M:TG which is just "play the deck [in your playstyle] that is the best at winning."
In M:TG I tend to enjoy swarm aggro, tempo, and prison. The clans that appeal to me most thematic wise are Lion and Scorpion, which I'm told matches pretty well. The LCG format makes it a lot easier to build a deck for everything, though, so I might just do that.
