A lot of runner will die to tag and bag, with the help of this card. The power is enough to be worth splashed out of faction, even at 4 influences.
First, I really like the mechanic that tag punishment remove the tag use to dish the punishment, I think it is a good balancing mechanism, especially to powerful cards. This also means that you cannot use two copy of this card to do 8 damages to a runner with a single tag. If you were to plan to do more than 4 damages, when there is 2 tags and more, you should use BOOM!.
To use this card is all about timing, since you need the runner to have 3 cards in hand or less AND a way to put a tag on the runner. The funny part is that in faction, you will have to rely on putting a tag on the runner on their turn, using Forced Connection, Overseer Matrix, Colossus, Mausolus, Pharos, Surveyor or Veritas.
If this is popular in the meta, it will encourage the runner to slow down their gameplay to make sure to have 4+ cards in hand.
The art and quote explain well the effect of the card and its name. For my part, I like art that look like comics and mangas. Great card!
