(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
