Is my yugioh six samurai deck good?

You should never have a "six samurai deck." Perhaps make a warrior deck with the six samurai within it or even an elemental hero deck (however this deck might take time and a lot of money). With a six samurai deck, the opponent should quickly get your strategy and you will lose. If you have a warrior deck, your opponent will not see your six samurai coming, and then you can get at him/her with more force. The six samurai are worthless on their own because their attack and defense are too low. Most of the opponents that you will face will quickly summon a 2,000 attack or higher monster quite quickly. Good luck.
