This complement bioroid defense perfectly. If the runner is clicking through bioroids, it will still punish by making the runner spend 5. If the runner spend the 5 and then trash Manegarm Skunkworks, that is a 6 differential (counting the cost of rezzing the upgrade). That is quite the differential.
Most Haas-Bioroid deck will benefit from this amazing defensive upgrade. The only downside of it is that it is unique. Which mean you can protect only one server at a time.
Good art, flavorful quote, amazing upgrade.
