Bane-Blades
and as you said an army, LOTS of them
hell yeah! come get some Chaos scum!
also, kill all big managers, destroy big enterprises (no wait scratch that, with money erased i need big companies to do my bidding), and somehow manage to destroy money in its entirety, as it is the root of evil and lots of problems we have, both large and small scale.
and pacify those troubled african countries. and south american. and asian.
then make the companies and enterprises get them some infrastructure, heave them into the 21st century.
then live happily ever after, until we explore space and find all them Xeno scum.
thousands of years of war will follow ^^
