>>5922471The frame for it looks like this. It's one of the smaller frames from Koichi, Rohan or Mista wedged between the base of the display arms. You REALLY want to make sure the two halves of the base plates connect solidly or you're bound to have an awful time.
Outside of that, if you want to get really crazy with it you need the clips from Kira or Ceasar to attach additional figures, a decent sense of balance and where to discretely have the display arms lean and figures hold on to one another so the whole thing doesn't topple and a fuckton of patience.
I've been meaning to redo my display, and if I can remember to I'll take a picture of what the display arms look like without the figures on them so you can see what an absolute disaster it is.
