When it comes to army building I usually see whats there. If there are a bunch of clones, I will take around 1/2, assuming there are more than 5-6 there at the time. If its one or two I will buy them depending on the figs from the sst left on the pegs. If all the others are there, I buy em, if there are someleft, I willleave a set for someone else. 2nd or 3rd time round, I goes for mines.
