This seems like a potentially very powerful card for criminals at first:
At 2 cost, it seems comparable to Inside Job, which is a great card for many reasons, and a big enabler for criminals getting past big taxing ice.
- Has the advantage that it can bypass any ice in the run and not just the first encountered ice. So, corps that try to harden a server against inside job by putting a cheap ice on the outside won't have success vs. this threat.
- Inside job can't be used to help you land another run event like Legwork or The Maker's Eye, but this card can. This card can also be used with Inside Job to bypass two ice (and perhaps multiaccess with The Twinning?)
However, it is also a lot less flexible than Inside Job:
- You can only use it on centrals, you can't use it to crack the remote
- You can't control which server is your mark, so if you really need to get into a specific central, this card won't reliably help you do that.
For Nyusha "Sable" Sintashta: Symphonic Prodigy the most obvious consistent use of this card is that it may help you translate Easy Mark into a successful run and a free click on a turn when you might not otherwise have been able to. So this card may enable opportunistic access, possibly more cheaply if the corp is playing big ice.
The argument against this card I think goes as follows:
In the new Cezve meta, centrals are already very porous. Cezve helps you get where you need to go no matter what your mark is. With Bukhgalter and Cezve you are breaking Drafter for free. With Corroder and Cezve you are breaking Gold Farmer for two. Instead of breaking Gold Farmer, you could bypass it, but then you paid two to install Backstitching. So why bother with Backstitching?
If there's something big enough in your way that Backstitching would be cost effective, Boomerang would probably also work, and Boomerang has a lot more flexibility and utility. You can use it to crack the remote also for instance.
On the plus side, Backstitching will always be able to help you on the turn where you play deep dive.
Overall, I expect this card to be somewhat niche.
