What Does Starsteel Daisho Do?
Like all legendary weapons, Starsteel Daisho lets your main character (avatar) get involved in the battle directly. Normally your main character can only attack once per turn when wielding a legendary weapon, but Starsteel Daisho can attack twice.
That can make it very useful for clearing off a couple of potential blockers in order to open the way up for an attack by your army. But note that each blocker will knock down its armour value, so it might not last long unless you boost it by using a car such as Reinforce.
Another option is to wait until you've already cleared out the blockers before using this card. Then it make two attacks directly on your opponent's character (face) without losing any armour.
