Is my six samurai deck good?(repost)?

Really not very good at all. All you have done is put all the six samurai cards you could find together. You are missing important cards like Mirror Force, Monster Reborn, Dark Hole, Torrential Tribute, Bottomless Trap Hole, Sakuretsu Armor, Book of Moon, and Dimensional Prison. A deck, if it wants to be successful will not run every single card of a certain type, it will run multiples of the good cards.
