We'll be coming back to this one when card rotation first hits in Spring 2017. This looks to be the first of likely many cards we will be getting that are tweaked versions of Genesis cycle cards incorporating lessons learned from years designing the game and watching the meta evolve. It will be interesting to see what Damon and his team indirectly tell us about how they perceive card and faction power levels through these.
Here, it seems like they felt that Snitch had an effect which deserves a spot in the Criminal color pie, but they likely felt that once it had hit the board in a deck designed for it was a bit too permanent and/or non-interactive. With Au Revoir and enough link to run Cloud breakers, a Criminal jack-out deck had essentially complete impunity to bounce off outermost ICE every turn no matter what subroutines that ICE may have, building free cash, free information from Reflection, and a free battery of multi-access from The Turning Wheel counters and essentially being untouchable for many Corporate archetypes until they made their unstoppable mega-run. Strategies like this one alongside powerful icebreaker tutors and overwhelming AI breakers are part of what have been contributing to a general meta environment of devaluing the ICE that corporations slot, and this drives Glacier decks away from the meta unless they can slot very specific answers to such decks (Executive Boot Camp is one such card that springs to mind).
I for one am glad to see this card, because it means that Criminals still get to keep an important part of their factional abilities without continuing that undesirable trend. Criminals may not be able to tutor up instantaneous answers to ICE, they may not be able to install one single AI Icebreaker and guarantee access to their target, but if they're willing to spend 3 and a deck slot they will still be able to pressure the corporation in the early-game without a full breaker suite and not jeopardize their lives and valuable programs. I don't know if GPI Net Tap will be a card that sees much competitive play after Snitch has left us, in fact I suspect that it won't, but I also feel that is fine. It is a balanced card that offers a useful ability, and it's a card that Criminals deserve (even if it's maybe not the one that they want).
