Think you've got it wrong. The bottom of the roster will always give up 3, as long as it 3's one of your low bases while contributing nearly zero to the war weighting, its done its job. But its just one account, not too hard to make up for with good attacks higher up.
Opponent had one in our last war, named "Experiment". Feel bad for the guy that hit it, hosed out of the war loot.
