Logjam stocks went up in the startup format with the ban of Pharos.
However, even if Pharos is present, Logjam is still good. Why is that?
First, it gets advancements for free. This synergize with Trick of Light and Hearts and Minds, which can use those advancements, without forcing the corp to first put them there.
Second, it has 3 end the run subroutines. Making it difficult for Botulus and impervious to Boomerang.
Third, on a face check, it gives back 2 to the corp, making this ice cost functionally 4.
Finally, it can have near infinite strength (helped by cards like Tree Line), contrary to Pharos, possibly making it impossible to break.
The big downside of this ice is that Hush put it at zero strength.
Art shows a log jam, in the literal sense of it. It is a bit hard to make out, because of the color saturation. It could have been a log (as in computer logs) jam also. Both work, making it a clever word play. This gives the idea of a big barrier. Ok.
