Data Loop is quite a good card. On encounter effects always add a nice little bonus to a piece of ICE. And there are now quite a few ICE with these effects. This, though, may be the best one yet.

Forcing the runner to return two cards from their grip to their stack is quite a nice effect. You are setting them back a or two as they will have to redraw their cards. But more importantly, they now have a smaller hand, mid run. Use Data Loop to protect agendas such as Fetal AI and Obokata Protocol, especially in PE. Combine those or other agendas with upgrades like Ben Musashi, Prisec and K. P. Lynn. Then there are traps. Perhaps you are at game point and so the runner feels compelled to check every card you put in your scoring remote. They feel comfortable checking that un-advanced card with the four cards they have in their grip. But after hitting the Data Loop, they suddenly have to seriously worry about a Snare! Especially since they don't have enough clicks now to draw back up and try again.

Seven to rez is on the expensive side, but so very worth it in any kill deck (any deck really as long as you have the money). With four strength and two subroutines, this will cost Paperclip only 3 to break, not great, but not horrible (because of the odd combination of subroutines, Corroder can actually break this for 3 as well, if the runner is untagged). Two influence means you can easily import all three into Weyland or Jinteki if you feel so inclined. Stack two or three on a server for maximum fun!

So I've said it before and I'll say it again. Hunting Grounds is a good card. Try to make room for it, especially if you are relying on an A.I.

I think you botched your last sentence. —

Can this flatline a runner?

On its own, Data Loop cannot flatline the Runner because the encounter effect is directly taking cards from the grip and placing them at the top of the stack, not actually dealing damage of any type to the Runner. If the Runner has two or fewer cards in their grip when encountering Data Loop, they would simply have an empty grip after the encounter effect resolves. However, this does make any follow-up damage from another source that much more potentially lethal, as noted in the review above.

My first thought on reading this card was, “Wow, that is insanely good.” And indeed is has quite a few comely attributes. The one problem though is Paperclip. Paperclip is a ridiculously good card, probably the best breaker in the game. I feel comfortable saying that it makes an appearance in most runner decks. Paperclip breaks this for just four. That is quite low for a piece of ICE with a rez cost of nine. Still, that will add up over time.

Now that that is out of the way, lets talk about the many perks of Tithonium.

-Tithonium is the fifth ICE immune to Parasite! Caissas and Egret too. This while still being about to host "cards" like Oversight AI, Rover Algorithm, and Sub Boost. Certainly a nice bonus.

-Tithonium is a Destroyer Barrier. Its mere existence forces the runner to have all three breakers or a solid A.I. in play before running or risk serious repercussions, in this case losing up to two programs and a resource. Bulwark is not nearly as painful.

-Tithonium can be rezzed by forfeiting an agenda instead of paying its rez cost. Use this if you are short on credits, are playing Jemison, or have a scored Standoff.

Other niceties are the fact that it is immune to Endless Hunger, it only costs two influence and that the card is named after a big @ss canyon on Mars.

Watch out for Knifed, Sharpshooter, and derez effects.

Immune to Endless Hunger. Yet another card that serves to demonstrate that Apex is meant to be nothing but a sideshow joke. —

This card is very good! As noted by Silv, if there are just two advanced cards on the table, this becomes better than Hedge Fund. But in the right deck it can make ludicrous amounts of money. Let's take a minute to compare to its obvious cousin Commercialization.

The problem with Commercialization is not that it only gives 1 per advancement token. It wouldn't be terribly hard to get four or more tokens on a card, therefore making this better than Hedge Fund. The problem is two-fold. If you are placing a bunch of tokens on a single piece of ICE, the runner is going to be pretty wary of it. He or she may just try to avoid the ICE altogether. The second problem is that you are putting all your eggs in one basket. If the right piece of Cutlery or a well timed Forged Activation Order strikes, then that whole investment is gone. Mass Commercialization avoids both these problems while also doubling the gain. Then too, it is influence free, so Tennin can spend their 15 elsewhere.

This card obviously finds a place in any Tennin, Because We Built It, or Builder of Nations deck. But it may well be good enough to influence the construction of other Weyland decks. You might consider including more advance-able ICE in your Building a Better World deck. Advance just two ICE and you'll get 5 with a play cost of 0. Remember too that the tokens to not have to be on ICE. Traps and agendas count too (and runner cards if you are playing as Tennin).

Now if you want to go all in with this card, there are several cards to consider adding as well. This includes, but is not limited to: Anson Rose, Space Camp, Satellite Grid, Shipment from Kaguya, Trick of Light, and Matrix Analyzer.

Builder is also a nice one. If the runner has reason to breaking its subs it becomes a quite taxing 4str/2sub code gate for 2 cred. —

So the website here does not reflect this yet, but this card did receive an errata. It can only be used on a "connection resource". So no more cheap troubleshooter plays. That said, lets move on.

This card seems like a necessary evil to me. Using this card will almost always force the runner to trash that connection. And to use 2 and a to do it. Because let's face it, if they were going to play "tag me", they probably wouldn't have installed a connection (there may be some exceptions, like the upcoming Jarogniew Mercs). This is quite powerful, as you can get rid of some of the most troublesome cards runners have access to. And the reason it is so necessary is because there are certain connections that completely undermine a specific strategy you may be employing. Seeing Film Critic hit the table when you are playing as Haarpsichord Studios: Entertainment Unleashed elicits a sinking feeling. Ditto if you are playing a Midseason Replacements deck (if you are playing this kind of deck though, I advise you to stop, it is a stupid card). Aaron Marrón is going to give any tag-heavy deck a hard time, whether you are relying on said tags to flat-line or just tax the runner. So MCA Informant can save the day, and without the chancy psi game. Hence the 4 play-cost seems fair.

The evil comes in the form of its interaction with another card, namely, Zealous Judge. After playing MCA Informant, you can rez Zealous Judge as soon as the runners turn starts. They then basically have to do the following right away: Get rid of the Informant, access the Judge, and trash him. I made a deck specifically to see if this was as easy to win with as I envisioned. And I went 7 for 7. I made it in Skorpios Defense Systems: Persuasive Power just for the smaller deck size. Almost all runners drop a connection right away. Hide the Judge behind a Data Raven and/or a Chimera and they are going to have a real tough time so early in the game. After they try and fail, just hit 'em with a nuke. Anyway, seems a bit too powerful to me, so I will not be doing it again.

"So the website here does not reflect this yet..." yes it does, —
I guess it does mention an errata exists for the card. I didn't notice that. However, it still says (much more visibly) under the Rulings, that you can install this on a Corporate Troubleshooter. —

A solid mod to help out many an icebreaker. Only Breach and Golden already have a pump-to-strength cost to match this. And only Sharpshooter is better (not counting stealth breakers).

Here are a few notable interactions:

Yog.0 - Under most circumstances, Yog will be able to break all but three codegates in the entire card-pool for just 2 (if it can't break it for 0 that is). Orion and Fairchild will cost 4 and Tollbooth will cost 5.

Mimic - For a long time this was the most used killer in the game. An influx of high strength sentries has curbed its use to that of a backup. Dedicated Processor will let it break any sentry quite efficiently.

Morning Star - Break all barriers in the game for 1 - 5.

Femme Fatale - A great card to get past those annoying Tollbooths and Data Ravens, but one that was super costly to use if you face-planted into an Archer without an alternative. Now break Archer for just 6.

Pipeline or Dagger - Use these in faction as your killer to save on precious influence (and memory in the case of Dagger).

The smart people breakers - You could try using Dedicated Processor instead of boatloads of memory to make one of these work.

The main advantages this has over Dinosaurus is that it is cheaper, and more importantly, it can (must actually) be installed after the breaker. This way you can at least make somewhat less risky runs with your Yog or Mimic as you wait to find your Processor.

As the actual icebreaker gains the ability, cards like Cloak and Multithreader can be used in conjunction with Dedicated Processor.

It is a Hardware so it is a bit more difficult to trash directly, but of course it will be trashed if its host is trashed.

A good card that I expect to see played quite a bit. Shapers will probably be importing Yog.0 and maybe a couple others. And I'm sure we will see it as a one-of in a few Criminal and Anarch decks as well.

No mention of Switchblade? It helps a lot with managing the stealth creds! —
Also a pretty decent mod for Inti. —
I agree it is pretty amazing with Inti. 0 to install the breaker and after that you can break Eli for 4 credits. —
Nice Review, but don't you mean Spider instead of Dagger? Otherwise the memory comment doesn't make any sense. —
@HyenaMars That's Creeper, not Spider. —
Can you install Dedicated then Adjust Matrix since the requirements to install are non-so and it becomes an AI after you install dedicated? —
I mentioned memory with Dagger because you won't need to install Cloaks. —
