Stormguard Warrior isn't readily in a Swordsage's repertoire, it requires Iron Heart maneuvers and a crappy feat(Iron Heart Aura). Besides, unless you have a way to lockdown a victim or attack many times immediately after Combat Rythm Stormguard Warrior ends up wasting your actions and/or letting the opponents have theirs. What a Swordsage is good at is being versatile and annoying because they get many maneuvers that allow movement outside where it is normally allowed and more of them. The Shadow Hand discipline has three manuevers that do teleportation one of which is a swift action, Desert wind also has one as an immediate action possibly evading attacks or spells. The Sun School tactical feat(Complete Warrior) can allow you to make any attack to anyone to whom you teleport by. Setting Sun has many movements as counters and even has a stance that allows you to burn AoO's for 5-foot steps to evade attacks.
A must feat though for anyone focused on a Swordsage is Adaptive Style otherwise you will run out until the next encounter. It fully replenishes your readied maneuvers with any one you know.
