I posted this on the CotD thread on Reddit, but it was longer and more interesting than originally intended.
'Deceptively good' is my analysis of this card, though I've yet to find the perfect deck to take advantage of it.
This card combos with a lot of other nice cards like Resistor (which becomes almost a popup) and Ash (better think twice about letting the trace fire then running again!). Things the runner would often let fire (like Gutenburg) suddenly make them pause. It's a great one have against a runner going tag me, as suddenly those 'just pile on more tags' runs are draining their accounts and padding yours.
With the help of a very kind stranger on The Facebook, I built an ArbTech combo deck which used Broadcast Square, Reality Threedee and Muckraker to put the runner in a real bind; you rez the broadcast square, then the 3Dee and fire the trace. If the runner doesn't pay into it, they lose 1-3 and you gain that much.
Then proceed to rez your other 3Dees and your muckraker, which then itself fires 3 traces and ends the run. At that point, slap down a Manhunt, rez a city surveillance, and watch the runner become truly miserable.
This deck was a bit janky but it had a load of crushing victories (losing only, weirdly, to Adam and Sunny). It was a bit miserable to play as and against, though, so I've shelved it for the moment.
I've tried ArbTech in other decks since. It's a lovely combo with Troll and things like Turnpike or News Hound, or especially with Manhunt, which is becomes drip economy. That said... I've not really had any luck using it in a 'standard' deck. It seems too fragile at 3 to trash, and you can't really afford to protect it too heavily. Maybe I've had bad luck to come up against rich runners, I don't know. I'll keep experimenting because I'm sure there's the nugget of a powerful deck here.
