A staple of Jinteki kill decks, this card relies on the fact that a ‘failed trap’ is often left alone. Install and advance advance and a runner will go after the card, assuming it to be an agenda. Install and advance only once, and the runner will stop to consider, look at the board state - maybe they won’t run. Maybe they will assume it is a trap and let it be. A few more slow advanced turns and all that is left is waiting for the runner to drop below three cards in their grip.
In combination with Industrial Genomics: Growing Solutions this is a rather common strategy, boosting the trash cost to high levels, in combination with Shock!s in archives and Hostile Infrastructure as an additional cost, leaving a runner in a potentially bad state. Ronin has other uses, and when played in the right manner is a great way to snag a kill.
