This card appears to be overpowered.

Turning off the runner ability is not going to bother most runners.

Turning off the corp ability will enable safer accesses and agenda steals.

This is another 3+ copies of Employee Strike without being on the MWL.

Maybe this is a knee jerk reaction, but I think this card should not exist.

This hammers a few Corps very hard: Mti, AgInfusion, maybe even Argus. But to others, this is waaaaay different than EStrike. —
"2019 MWL: Announced 22 April 2019, Effective 3 May 2019" it's hurts mostly op corps, and it's perhaps with ES and Film Critic removal on next MWL in mind. —

Not really. NO, absolutely not. If you are running Mti or AgInfusion, just use their ability after Direct Access run. Just block them with border, batty, nisei, etc. than use your ability as nothing happened. —
This card gives you E Strike for 1 run in exchange for: —
>_< Anyway, this card blanks the Corp's ID for one run and cannot be combined with other events (such as Stimhack, Maker's Eye, Diversion, etc). It's a very tame implementation of E Strike, and I think it'll be hard to slot them. —
Good to see this sparked a little conversation. I'm still not convinced. I shall see once I start playing with it. —
Does this event remove the Runner's link? It's very odd that it uses the strange wording 'loses all abilities'; how does that differ from the standard 'identity text box is blank'? —
We'll have to wait until the update to the NISEI Rules Document is released to find out. That should be next week. —
This hurts Haarpischord Studios a lot. :( —
Now that MWL 3.2 has thankfully axed ES, this card is the best answer to corp IDs that punish you for running. It'll be interesting to see how much play this'll see now. Even though Mti has also been shown the door, there are still plenty of IDs which are hurt by this card and its self-recursion means slotting just one or two should be enough. The inf cost is a pain though. ES also cost an inf but was much stronger so it'll be harder to justify using one up to slot this. —

Jank review.....

Install The Black File

Do your thing for remaining three clicks and next 2 turns.

On the turn you would place the third counter on it sell it to Aesop's Pawnshop instead.

Somehow bring it back to hand.

Rinse.

Repeat.

Get killed by BOOM! or Jinteki.

edit: this wont work as pointed out below. Sad panda :(

the moment it gets trashed the Corp can win by points they scored while it was active, so you can't extend the duration by recycling it. —
Good point, well made. :( —
What if, instead of selling Black File, you trash it by installing another copy of it? —
One per deck. —
Now this review is stuck here for all eternity... —
To add something that has not been mentioned, this can be spicy in a Leela/Gang Signs deck as now the corp has to care about the last agenda they score as well. —

A dream scenario was presented to me last night.

Have 3 Persephone installed (including supporting memory hardware).

Have 3 Diesel in hand.

See a Komainu.

Click 1, 2 & 3 play Diesels. Click 4 run said Komainu with its 11 subroutines (assuming you started with a full hand of 5).

Trash your hand to Komainu. Trash 3 cards from your stack to activate all three Persephones.

Corp trashes 33 cards from R&D.

Rejoice in your one in a million play :)
