There are certain advantages to using each sword type. In worlds 1 to 4, you can use any sword you like and generally the swords you want to level up. Later parts of world 4 and all of world 5 have much heavier artillery damage so it is prefered to use bigger swords ie Uchi/ Tachi/ Oodachi/ Yari for their survivabilty and tantous are unused because of their limited troop slots. World 6 is all night battles giving Tantou and Waki big stat boosts while reducing Tachi's, Oodachi's, Yari's and Naginata's. Tantous receive a really great boosts so teams are mostly composed of tantous. There are more situations where each sword shines but having a solid team for Day battles and another for Night battles should be your goal


 * Day battles - Tachi/Oodachi/Uchi are preferred
 * Night battle - Tantou/Waki/Uchi are preferred
