I'm convinced that this card is extremely strong in Shaper, given the current Corp meta. Shapers do not have a good answer to the current mix of HB Foodcoats ice in particular, which is usually some mix of Ichi, Assassin and Vikram. Atman 4 makes you vulnerable to the latter two, Atman 5 to the first, so Atman is not a good solution. Cyberdex makes Datasucker support problematic.
However, all three of these are tracers, all are broken by Gingerbread for the same cost or less as the rez cost (which is a fair measure of whether a breaker is efficient).
It also backs up your Lady against NBN match-ups, meaning you can use Lady for Wraparound and Gingerbread for Resistor. 5 credits for Archangel seems bad, but that's the same cost as Gordian. 5 credits for Gutenberg is also bad (given that paying off the trace is 7), but if you're click starved rather than money starved (a common scenario) then paying 5 to avoid the tag and keep your clicks is better than paying 7. However, if you add in NRE then suddenly Gingerbread is one of the best breakers in the game for dealing with Archangel and Gutenberg. It's also as efficient as Mimic at breaking Caduceus.
Given that Yellow and Purple are the dominant corps right now, tracers are everywhere. Gingerbread deserves a second look to fill out your Shaper breaker suite. I have not been disappointed with it.
