This deck is part of the third iteration of the Project CROW mini-campaign for beginners familiar with System Core 2019. It consists of three Runner and three Corp decks, that are built up over three steps. They start at the System Core 2019 with a few additions and end up with currently competitively viable decks that have placed well in tournaments.
This is the first step towards the archetypical ice destruction deck. You are probably already familiar with the basic framework of breakers from the System Core 2019 setting. Additionally, you're getting Chisel and Devil Charm, which in combination allow you to blow up ice on approach, so you don't even need to encounter and break it at all. You need to balance preemptively installing Chisel as a pseudo bypass with running into ice with your face and making them pay the rez cost, just for you to then install Chisel on it and blow it up on your next approach. To have more flexible access to your Chisels, you have Simulchip, which allows you to fetch a Chisel at instant speed. You can actually do this in reaction to the corp rezzing a piece of ice.
The other addition to the card pool are Paladin Poemu and Keiko, which are from the group of companions introduced in NISEIs Ashes cycle. While Keiko gives you the memory needed for installing your Chisels and Datasuckers, it also provides additional value together with Poemu to install all of your other things.
