You can make a straight up bard that is a terror in a straight up fight, but starting off with satyr HD does not help.
One version is the invisible, Battle Caster bard in mithril full plate with mirror image, self-hasting, using touch of idiocy and Arcane Strike.
Another version has Greater Spell Focus in both illusion and enchantment, which can be a very bad day for someone.
Then there's the "surprise bard," like the one with the undead affecting feat who has ghasts serving him, an Arcane Disciple with the Fire domain, or a maxed out Use Magic Device skill and a wand of force missiles.
