Shinsengumi are samurai, not knights. Also the Knights of the Round Table is mythological, and Legend World is all about Mythology. Plus the knights he uses seem to be in BT04 along with the other Legend World stuff, from the looks of the poster (it's on the Booster Sets page if you want to see it).
