Also, Death Strike Bracers from the MIC allow you to SA many things that are normally immune 3/day at the cost of your swift action. Thats about as good an action economy as a Wand of Grave/Golem/Vinestrike. They don't have an attunement period, so in theory you could buy multiple pairs and swap them out between combat, or simply beg/bribe/sleepwith your DM to allow you to combine several pairs into a single item with more charges.
