(system core 2019 perspective) Ever wanted to bang a piece of ice with a stick of toblerone until it shattered? Well now is your chance!

Synergies

I would like to think that this card and Femme Fatale are the best of buds. Femme takes care of ice that have high cost, high power and low number of subroutinrs, while toblerone takes care of the high cost, low power ice. Glacier decks beware! (Huh. Who was that? Probably just the wind

With enough deck recurrence such as Test Run and Retrieval Run, this card can be used to get rid of pesky low cost ice such as Afshar, Rime and Congratulations!. Heck, with enough deck recurrence, this card can be used to blast through low impact gear check cards such as Wall of Static and Enigma. You thought that one ice could protect your r&d for a few more turns? NOPE, your server is naked and I just played The Maker's Eye

Considerations

I feel like this card creates a really interesting set of questions to answer: Is this ice worth chiseling? Should the Corp spend his turn clearing virus counters if chisel is installed on an expensive piece of ice?

With this in mind, one of the keys of this card would be placing the Corp in a situation where cleaning the virus counters or leaving the counters be will both result in a situation that is pretty annoying for them the corp. How this can be achieved, well, I am a bit of a noobie so I don't know a good answer to that. Maybe threatening multiple servers, one with chisel and one with other resources, will be the best way for using this card.

Final thoughts

I would like to take a second to appreciate how well the art, name, flavor text and mechanic of this card go together. Kudos to NISEI for such a thought provoking and nicely designed card

Looks like you've got The Nihilist confused a bit. It places 2 virus counters on itself, not the virus program. —
Anyways, if we're really talking System Core 2019-only, then mention should be given to memory consideration. In the core, Anarchs are generally going to be stuck with 4 MU already being filled up: their 3 icebreakers and Sucker. Therefore, it's best to play this with a few Akamatsu MemChip slotted so you won't have to worry about MU issues ever. —
Oh dear, yes, for some reason I thought nihilist worked like Grimoire. I'll delete that part of the review. And yes, you are right, this guy will demand more memory to be used reliably —

(System core 2019 perspective)

When I first looked at this card, I thought to myself "wow, this looks like a worse version of Inside Job or Spear Phishing". But then I thought about it a bit harder and realized that this card actually takes care of the one annoying case spear phishing and inside job fail at: what if the big ice is in the middle of the server?

Quite often, when playing against criminal, the Corp will sandwich their big ice between two lower cost ice to ensure the big ice is not bypassed by the spear phishing/inside job suite. But that's where this card comes in. You can pay through the first ice, hit an "end the run" subroutine of that middle ice, and use the second run from this card to bypass that big annoying ice and move on to the tiny innermost ice.

Since jacking out is considered an unsuccessful run, this card has great synergy with Flip Switch. If you see a scary sentry or any other big ice whose "end the run" subroutine is non-existent or after scary subroutines, you can use flip switch to jack out while encountering the scary ice (assuming the ice does not have a scary "when encountered" effect) and then bypass that ice during the second run part of this card

A bit of a jank but interesting effect: if there is a semi annoying 2+ strength ice in the outer side of the server which you can go through without the aid of this card, you can use this card in conjunction with Chisel to lower the strength of that ice by two within a single click, making it much softer and easier to destroy. Similarly, this card can create a lot of problems for Sandstone due to this exact reasoning

This is my first ever card review. Please let me know if there is a way I can improve myself. I would like to write reviews for more downfall cards from a system core perspective, but would like people's go ahead before I continue to do so.

It also saves clicks when faced with "End the run" effects like Border Control and combos with The Turning Wheel for extra tokens. —
You have my go ahead! —
Thanks Whitemage7, I will make you proud :p —
@NOR5E thanks for the input. You got my jank engines all fired up —
