An ice tailor-made for Pravdivost.
In most NBN decks. this card is just kinda ok. Its subs are good, having both a somewhat painful face-check and an ETR. But at 5 cost, it isn't exactly cheap. Sure, Tollbooth is even more expensive, but it has a 'guaranteed' "lose 3 credits on encounter" ability that doesn't require any upkeep on your part. And at 5 strength, it is very annoying to break for Black Orchestra, as a nice bonus. You could advance this ice manually, but spending a click and a credit to make the runner lose 3 during a run on one specific server doesn't seem great. Still, NBN can always use more code gate options. On the cheap you have Authenticator (Pop-up Window doesn't even count imo) and funnily enough you often see Enigma. The aforementioned Tollbooth is the BIG one. At 4 - 5 credits you have Archangel (pretty good), Funhouse (good in tag decks), Peeping Tom (eew) and Sandman (EEEEW). Especially in a glacier deck, Mestnichestvo might see play due to being straightforward.
However, in Pravdivost this card becomes a beast. Because you can keep charging it for free, I think Mestnichestvo goes from ok to great. A 5 cost ice that cost the runner 6 - 7+ credits to get through every time is nice value. My big complaint here is that your ability is only once per turn, and if you are constantly using it on this ice you won't get value elsewhere. Still, on turns where you don't have anything else to advance, you can just keep parking counters on Mestnichestvo. Too bad its ability is only once per encounter. Vasilisa + this also allows you to trade more efficiently with the runner (1 of your credits for 3 credits of theirs), so you can use your ability for other purposes.
So yeah, neat little ice. One of the backbones for 1 ID's ice suite, and might even see play in other NBN decks. Probably not out-of-faction. Except maybe Eternal because of Tennin Institute. Is that a thing? I assume it isn't, but then again I usually stay with Standard and away from the shark-infested waters that is the Eternal pool. Anyway, happy to have Mestnichestvo.
EDIT: Oh god, I just remembered Cayambe Grid is a card in not-Standard...
Built to Last may also like it enough to spend 2 inf, as it's much better when charging it up pays you a credit— Greasythumb
