For the netrunner that likes to run the net. two of each breaker for multiple reasons.
Its cheaper to install from hand than use an SMC.
it's quicker to find breakers.
Paragon its like desparado but less influence and helps your draw
Oracle May not sure about this one although she makes alot of money when Paragon is up a running she dose sit in hand alot if i haven't got the console and she costs influence where as Symmetrical Visage is useful all game and inf free. Have to experiment with this one some.
Study Guide a really strong breaker when you can boost with recurring credits and you have at least one every turn which is ok 2 would be better ofc. study also gives you a breaker that doesn't need pumping late game this coupled with Gebrselassie means you can make runs with 2 breakers with little to know pumping.
everything else is pretty self explanatory really.
