I think this card is thematically great and that an evasion-first Finn deck built with Illicit cards is extremely fun to play and very formidable in solo standard and hard. I concede that you generally only want to bring one pair of mulligan-worthy economy cards and that most rogues will want to opt for Lone Wolf. Even with Finn, especially on higher difficulties, using Lone Wolf for consistent stat-boosting is a pretty tried-and-true strategy. That said, when played early, the additional actions and advantage managing opportunity cost provided by Fence is a huge boon, especially in a lean Finn deck where nothing costs more than 3 anyway and a couple of Pay Day or Emergency Cache is usually enough to play a few key assets and a stream of cheap events. While Fence does share the same drawbacks as other economy/set-up cards (bummer if you don’t draw it until late, bummer when you draw the second one), the cards it interacts with are quite good on their own and there’s nothing sitting in your hand waiting for a dependent combo.
Playing Fence early has generally provided me with three to six additional actions in the scenario. With Finn, they’re often used after evading an enemy when getting a few things done and moving on in the same round is crucial.
Some synergies with Fence and Finn:
Pay Day - upgraded from a more complicated Emergency Cache to an actionless 3+ resources
Smuggled Goods - from a somewhat lackluster draw to the same as drawing the Fenced-up version of Lockpicks, Lupara, or Pay Day
Lupara - obliterate the enemy and still move or investigate in the same turn
Lockpicks - this card just seems to love being fast; sometimes with a good opening hand, you can start on a 1-clue location, play Fence, draw a resource, then drop Lockpicks and get the clue before your first round is up
The interaction with Finn's Trusty .38 and Switchblade is less significant but helps to mitigate the initial cost of Fence.
The opportunity cost consideration is hard to quantify but feels very real when playing. The easiest example is when the encounter deck is throwing Corrosion at you and discarding Lockpicks feels a lot less painful when you didn’t already pay 3 resources for it. In smaller ways, it helps with managing resources and hand slots throughout the scenario.
As a side note, I don’t think the upgrade from Sleight of Hand is painful or that the card is particularly missed. The only really great SoH combo is with Lupara and I’d rather not wait on drawing both cards. (Lupara is still excellent with Fence, dependably performing its task of killing most enemies in one or two actions.) I know some rogues like Sleight of Hand for Lockpicks but with Finn investigating at 8, I’ve never run out of supplies before the scenario ended or the encounter deck ate the card. Just playing Lockpicks fast is the better option. I found that Sleight of Hand would often sit in my hand or get used for the heck of it and that I would rather have drawn one of the many available skills or events that more directly help me kill things or turn bad results into good ones (there are really so many to choose from for rogues).
There is definitely a fun factor element to this card but having Fence out provides a ton of benefits and feeds so elegantly into the Finn solo experience of rushing around and mostly leaving enemies in the dust except for a few big offensive rounds that I would highly recommend giving it a shot if that style appeals to you.
