Why Rapid Draw power and Iaijustsu? Isn't that redundant?
a Melee Attack with a Blade is a complex Action
Iaijutsu transforms this in a fast draw Action ( = the first Attack (right from the scabbard)becomes a simple Action)
Rapid Draw turns a fast Draw simple Action into a free Action
so this combination makes the first attack (as long as the Katana is in a fast draw Scabbard) into a free Action.
Zatoichi can still attack only once per Phase and any subsequently attacks are standard komplex actions, but his first Attack ist ...really fast (and he still has 2 simple or one komplex Actions but no more Attacks)
with a very fast first Dance
