the other side's lawyers might like a few wild-cards (as to increase the chance of a hung jury). No, never. The defense never wants a hung jury, because the prosecution will just get another chance to have another jury trial, with a new jury, but having learned from the failure of the first trial. The defense always wants finality. Prosecutions don't want hung juries either, because there is always the risk that the judge will either dismiss the charges (if more than half of the jury leaned toward the defense) or pressure prosecutors to offer a better plea deal to avoid wasting time on a new trial. Usually people "too knowledgeable" get bumped from the pool If by that you mean people who know too much about the case already, then yes, because the defendant deserves a fair trial. If you mean people who are "too knowledgeable" in general, then no, unless it's clear that they're going to take this "knowledge" and rely on that "knowledge" instead of what is presented to them in court. Lawyers generally try to exclude tech bros, because they think they know everything about criminal law based on watching a few episodes of Law & Order and CSI.
