Warrior Deck improvements?

May I suggest using 2 Royal Decree's, instead of just one because it could definitely increase your chances of drawing that card. Also, if you take a look at the forbidden list, you will see that Ojama Trio is forbidden and that you are allowed to have up to 3 Marauding Captains in your deck. If you want, you could add an Ultimate Offering to summon 2 Marauding Captains in 1 turn as well as summon 2 other level 4 warrior monsters because of Marauding Captain's effect. This way, you can summon 4 monsters in one turn. Ultimate Offering could also help you summon monsters during your opponent's turn.
