Here is a rez effect that you want. Give the runner 2 to break only one sub. Usually, the runner will chose to break the 2 damages sub, allowing you to draw 2 cards and give a tag. A great card in NBN: Reality Plus.
At 4 for 3 subs and strenght of 2, it is quite a reasonable price to pay. Bukhgalter will have to pay 2 and most other killer will have to pay 3. Of note, MKUltra would need to pay a whooping 6 to break all of it (the runner will probably let you draw 2 cards). So, it taxes reasonably.
This is a fun addition to the NBN ice suite. It is a good facecheck and a good tax, but will not stop the runner ultimately. At 2 influences, it is actually worth it to use out of faction, when the game plan is around taxing the runner rather than stopping the runner. With 3 subs, it is taxing for Endurance and Botulus to pass.
Unsmiling Tsarevna refers to the wife of the successor for the tsar. Putting the "unsmiling" push the concept of not being able to break all the subs (in a certain sense).
The art is nice and the color give the character a distinctive (if somewhat old) virtual feel. However, the strong colors makes the lines less defined. I think it is a deliberate choice and it reinforce the feeling of a virtual guardian. Well done.
