Now that R&D Interface, Medium and Keyhole are rotating, this suddenly looks a lot more appealing as a pseudo-multiaccess replacement for the aforementioned.
Equivocation gives you the option of sending the top card of RnD into the corp's hand and try your luck on the second instead. The benefit of this is twofold, both upping the chance of finding something you want to steal or trash and mitigating the risk of running into traps like Snare!, News Team or Breached Dome. The downside is that if the top card is an agenda or something you can't let into the corp's hand, you don't get any second access. Further, the effect can be very nice for the corp- a free certified non-agenda draw is great under most circumstances.
