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.

This looks very strong. A 7-strength, $4 sentry will surprise a lot of runners and it looks to be the most reliable program-destruction printed in a long time.

Major matchups

• It ruins Aumakua. There are not many ice which can surprise a 5-6 strength turtle and Stavka's the most broadly useful in its price range. Turtle decks tend to run rather adventurously and you will find opportunities to destroy them.
• Against MKUltra, it's reasonable value-over-time. It costs you $4 and usually costs them $3 to break. And maybe you snipe like a Botulus or Fermenter on first encounter.
• It produces very little value-over-time against Bukhgalter, Echelon and Na'Not'k. I'd suggest waiting on the rez as long as it takes to find a window where they'll be unable to break the subroutines.
• A runner exploring with Engolo will have a very bad time.

Stavka's value is heavily short-term, so you may find experimental uses for it with Nanisivik or (!?) ZATO City.

...

The card's power level is reasonable, but I think the card will be unfun. Losing 2 icebreakers (or economic programs) is unusually severe punishment on an ice which will usually be a 7-strength sentry on facecheck. In the spirit of not having a game end because you already discarded a backup breaker or you're in a mini-faction that can't reasonably stock multiple copies of breakers/recursion or are just sick of conspiracy breakers, I'd suggest giving the runner a costly option to prevent the program from being trashed.
