In a typical combat encounter, Saijo begins in the Caged Sun stance.  She might start by flexing into a combat feat as a swift action (probably Deadly Agility for extra damage), then shifting her veils into more combat-oriented ones as a move action (probably Armory of the Conqueror or Armlets of the Shaitan).  For her standard, she'd probably initiate a strike such as Ruby Zenith Strike.
