I think it depends on a few factors, the main 2 are the size of your area to display, and the price you buy them for. And army building really only applies to non-MOC collectors. But I'd say minimum 3-100 just depends on the price and the area to display. If my walmart had 1 peg full of multiple man on clearance for $1-2 I'd take em all, if they're full retail then I'd grab 1 maybe 2 and piece it together over time. The best figures for it are shield,aim, hydra,ninjas and skrulls, and out of all them I'd say shield is the most expensive as they only came in the 3packs. Skrull and Hydra would be tied for 2nd and aim and ninjas definatley the cheapest. My problem with army building is justify the cost, of spending $50 on 5 figures that are all the same versus new figures or a big figure, to me army building comes in to place to help bring in new stock and to give yourself an excuse to buy figures when there's no new stock in.
