I've used the same mag for 3 of my characters.<p>You may call me poor, my chars always borrow stuff from each other. ^_^; Weapons, Mags, slotted frames..
Katanas are a very good weapon with the God Battle in hand. You just need one strong enough to do decent damage. The saber is incredibly fast. Too fast actually, you still get hit on the third shot because to attack him while he is stunned ("him" is an enemy).
Partisans are faster and don't take off EVP.<p>I have three katana weapons. Two different. Just found them with my Viridia HUnewearl. They are strong, but the combo isn't good for my taste.
