An interesting deck you've got there, though it may help if you put some more of the traps that benefit the six samurai in there. Here's a couple of cards I'd recomend.
Breakthrough: You gotta love a card that allows mass direct attacks, even if your opponant still has monsters. combine this wiht A. Forces and a full field and you potentially have a one turn kill.
Swiftstrike Armor: perfect for special summoning Six Samurai quickly, and since it counts as a special summon, no succumbing to the ever pesky trap hole.
Shien's Castle of the Mist: for the simple fact that it weakens your opponant's monsters by 500 when they attack.
Backs to the Wall: when in trouble, play this and gain your entire field back, also good to combine with Breakthrough and A. Forces.
I'm confused as to why you have Morphing Jar in there. Marauding Captain, Command Knight and Exiled Force make sense, but Morphing Jar doesn't.
