2 legs back one front tent stakes, slim metal one,
One newer trick ~ a piece of PVC pipe that can fit over the forward leg, with a 45° angle piec on the end - you'll want it to fit kind of snug.
I have used this both indoh' (with duct or gaffers tape) and outdoh' (tent stakes).
I have used 3/4" PVC pipe which fits over my stand leg, it raises the front leg enough that that the stand is wither vertically straight or nearly so.
the piece of pipe I use is only about a foot long and can attach to the outside or inside of my bag - it could even slide over the top of the stand.
I thought about painting it black to be stealthy, however I like the bright white as an alert for wookies.
