The three stages of "It's a Trap!":

Stage 1: [reads the card for the first time] "WHOA THIS IS GREAT"

Stage 2: [re-reads the first sentence] "Wait... when exposed? This doesn't seem that great."

Stage 3: [filed into your collection, never to be seen again]

Since exposing is very underutilized in Netrunner, it isn't very likely that the net damage will ever land. (Unless you are playing against Silhouette: Stealth Operative, but she isn't very popular either.)

Trashing a program for a click and two credits is good value, but it's the runners choice, which severely limits the punch in the mid and late game. Also, if there is a Crypsis or Overmind on the board it is worthless.

At 3 influence, it's not even likely to be splashed, so there is no surprise factor with it being played out of faction. All in all, a very weak trap, although the flavor is fun.

It's high time we had another look at It's a Trap!, with the rise of a certain turtle into the forefront of the meta. For those who can't be bothered hovering over the link, Aumakua is an icebreaker that partially relies on exposing cards to build strength. Traditionally the Corp hasn't had much in the way of protection against exposure, save outliers like Akitaro Watanabe (who is no longer with us), and this card here. Surprise! A Runner using Infiltration, Deuces Wild or some other exposure mechanic (Silhouette comes to mind) will find themselves blasted in the face. Downsides are that this trap is unlikely to be fired more than once, and as a 2-to-rez, self-trashing ICE with a mediocre subroutine, it's barely worth the effort to include in your deck...

...but wait, what's that I see there on the Martian horizon?

Is it that time of year already? When the weak sun rises over the planting domes, and it's time for our Mandatory Seed Replacement? I guess it's time to get Replanting...

Historically Jinteki has had a few tricks like the ones I've just mentioned, like the now-set Sunset, the single-option Tenma Line, and the semi-inversificatory Mumbad City Grid. But the Red Sands cycle really kicks this sort of shenanigans into high gear: Mandatory Seed Replacement allows you to shuffle all your ICE around, and Replanting allows you to install ICE into nasty positions without paying the install cost. These two cards together can let you play cup and balls with It's A Trap!, re-hiding its hidden information and forcing the Runner to be extra careful about using exposure tactics. This either means they have to dive into Archives/open remotes for Aumakua tokens (always a bad idea in Jinteki), facecheck ICE (also a bad idea in Jinteki), or bite the bullet and expose things all over again (now with extra traps!)

Now if only its subroutine wasn't so terrible...

tl;dr - It's A Trap has some potential in an Aumakua-heavy meta, and synergizes well with Jinteki's native ice-shuffling cards to make the Runner nervous about running. However, it's still not that great. I would say the changes in the current meta have maybe bumped it up from 46th card to a maybe-include for a specialized Chronos Protocol or Potential Unleashed deck.

Real good against 419: Amoral Scammer and GPI Net Tap. Just like Psychic Field. Uh. It's also highly inconsistent. Just like Psychic Field. This card is probably never worth rezzing. It's on expose effect is the only worthwhile thing about it.

How does accessing archives work? Are upside-down cards "Exposed" at time of access, then selectively accessed, or are they simply in limbo waiting to be "Accessed"?

Wondering how this would interact with something like Industrial Genomics.
