So, Enforcer is a weird card, and one of the most interesting cards in Old Hollywood. Its most obvious comparison is Archer, the other piece of ice you have to sac an agenda for. It goes without saying that a five strength four sub sentry is enormously taxing to anything that isn't Switchblade, even if it can be clicked through. And all of it's subs are high impact! Kind of. Let's break it down sub by sub. Like Archer, you really shouldn't be rezzing this if you don't expect the subs to fire.
Trash 1 program - This is a high impact sub against every good runner deck, and is probably going to be the first sub to get clicked through. However, without the power of an ETR sub, this requires another piece of ice to be effective on a remote.
Do 1 brain damage - Yay dain bramage! But you only give the runner one. And without some more brain damage to back it up, one brain damage is pretty underwhelming. So this sub is only going to be relevant to HB lists with a decent amount of support for brain.
Trash 1 console - So this sub is going to be effective against most runners. I mean, seriously, what top tier deck doesn't run a console? This sort of antisynergizes with the first sub, though. Trashing a program will free up memory for them that they can spare when they trash their console. Another one of the downsides to this sub is that once it fires once, it's more or less a dead sub - trash the runner's console, and they have no console to be trashed.
Trash all virtual resources - And now we get the weirdest subs in the game. If you're playing against a stealth deck that somehow doesn't have its Switchblade or Dagger out, congrats! Kill those Ghost Runners. Otherwise, a lot of decks run one type of virtual resource or another and this will hit maybe 50% of decks with some force. Again, it suffers from the downside the previous sub has, being dead once the runner hits it once. The most obvious synergy with this sub is the Power Shutdown - Jackson Howard - Accelerated Diagnostics combo, but then we're entering all kinds of crazy combo Christmas land.
So overall, a damn strange piece of ice. I have no clue how playable this is, and it might be very meta sensitive. I don't think it's better than Archer, but someone will find a way to make it work.
