I've read reviews of this card all over the 'net, and watched the debate go back and forth about how good it 'might be', or how good it 'probably isn't' - but there's not been a lot of commentary about how it actually plays.
Please remember, I'm no world-class player. That said:
This card is far, far better than it seems - especially in shaper, where it can be situationally pulled out and applied to the game at hand. This card does three very nasty things:
1) It is a run event with the amazing phrase 'you may' right in the center of the card.
This means that the card neatly circumvents Enhanced Login Protocol, which is always nice. It also means that the corp isn't entirely certain whether you intend to use the card for the duration of your run, and they can't be certain of your target. They have to decide whether to rez all the things, or watch their carefully constructed servers slowly lose things that have cost them clicks and tempo to install.
And, if they do rez? You access R&D anyway.
2) It allows you to (fairly safely) cause the corp to remove potential traps or other nasty surprises when you can't afford to face-check or gut-check a card in a server.
Essentially, you can return these items to R&D, where a shaper can deal with them at their leisure. Just not sure what that card is? Torn between a Snare and an unadvanced 3/1 for game point? Just go stuff it back in R&D and buy yourself both time and tempo.
3) It causes suprisingly large tempo hits to the corp.
Because the card goes to R&D, and not HQ, the card is basically 'lost'. Whatever that is is now mixed in with whatever the corp has still got to work through - if it was vital to the corp's strategy, it's likely now gone.
And you? You, the runner, you don't lose tempo - if they rez their things, making them invulnerable? You just access cards in R&D anyway, and enjoy the fruits of your successful run.
It's worth noting that this card combos surprisingly well with John Masanori, giving you a dreamers run and a free card, so your own steps don't falter. It has an obvious combo in the overlooked Exploratory Romp, which can let you revoke tokens and pick up something that they've /really/ spent effort working on.
That combo, should it come to pass, is a direct counter to Mushin no-Shin, allowing you to rip off all of the tokens and stuff the card back in R&D without ever bothering to access it.
Having now played the card in a Kit-themed runner deck? It definitely punches suprisingly above its weight class. Once it hits the table, the corp now has limited options - it allows you to work solely in R&D, target remotes, and ensure that the corp has to advance important things lest they simply be drowned in other cards, made available for your heavy R&D access. It shines against Personal Evolution and Replicating Perfection decks, and does very well with NEH, at least in local matchups.
It's definitely more useful than it seems - especially in faction, where it's easily tutorable if needed, or ignored if not particularly useful in the current match.
