Here’s the Val deck I’ve been on. Dumblefork shell is still the best, until some crazy meta shakeup happens.
The flexible slots are 1x turntable, 1x scrubber, 1x clone chip. You could throw in some combination of career fair (although I think the deck has plenty of econ), employee strike, film critic, clot, or even blackmail. I’m personally against blackmail in the dumblefork shell because it goes against your game plan of being able to Faust in anywhere, and then punishing rezzes by destroying ice. That said, blackmail does have a lot of teeth early and just the threat of it does a lot.
The biggest influence splashes are rebirth and e3. Rebirth into ed kim is an amazing card vs palana. It makes running hq much more profitable, and medium digs can go a lot deeper. I’ve rebirthed into Eddie at least half of the time I’ve drawn rebirth. Most of the other times, rebirth is a very cheap and powerful scrubber, but quetzal (especially with e3) can do lots of work vs a blue sun that thinks they can lean on Navi mumbad city grid.
E3 is a slightly controversial card, but is definitely worth a lot. In Valencia, the bad publicity means that you save a card every run if you hit a multisub ice. This allows you to run a lot more often and more aggressively. Obviously, it gives hb, and any other deck packing eli/ichi, fits. One of the most important things that I feel is overlooked is that it allows you to conserve a few David counters vs otherwise problematic ice like assassin, curtain wall, and ichi 2. (not to mention turning little engine into a never-rez ice!)
P.S. Sorry, no DLR this time.
