Stavka is a contender for best destroyer ever printed.
4 credits for a 7 strength, two sub destroyer makes you question what you were ever doing playing Rototurret, and Rototurret has seen a fair amount of play. It's similarly tough to facecheck as Archer, but doesn't constrain your agenda suite or put you behind on points the way Archer does. The "trash a card" downside is real but does enable some neat finesses, like trashing an agenda that you would otherwise lose. If you're playing Ob Superheavy, the trash ranges from "mildly inconvenient" to "enables game winning shenanigans." Players will note that this is answered by Boomerang, but what ice isn't? The trash is optional, so you can let the runner pop the Boomerang even if you don't trash anything. Despite being a mediocre ice for taxing on turns after the rez, I think that this is so powerful that this will see play in other IDs and out of faction.*
*What's this asterisk doing here? Oh yeah, two metagame threats that make this card sad.
First, the conspiracy breakers. Trashing Clippy is an annoying 4 credit tax on the runner, but won't win a game by itself, and until it either rotates out of standard or gets banned, everyone and their dog will probably be playing Paperclip. The full conspiracy suite is less common, and you'll probably have support programs you can smash instead, but this does lose some of its absolute game-destroying potency that you might have hoped to see. The silver lining is that MKUltra is relatively inefficient at breaking it both on rez and on future turns.
Second, the Boat. Endurance very neatly answers this on rez, and it'll be very very hard to try to slam an Endurance runner into Stavka when they're out of boat counters and also don't have money to break with a killer and also have programs you can trash. The boat seems primed to be a serious metagame threat in the upcoming era of Netrunner, and particularly hoses the kind of fast, rush-based play that would otherwise love a big meaty destroyer faceplant.
So, in a vacuum: Stavka is amazing. Premium efficiency ice, capable of winning a game outright, very hard to play around. In a meta where the boat and conspiracy breakers are extremely common, Stavka is probably very sad.
