This card does not get enough love. Let's talk about just a few of the wonderful things forfeiting a Falsie can do for you:
Got bioroids? Don't want them to get click/e3'd through? False Lead says you're going to slam headfirst into that Heimdall.
The runner found a Snare? Hold that tag and 3 damage in yo chest, son.
Argus LOVES this card. Make your damage and tags stick. If you slam out a Falsie early you can scorch them on your terms. Whenever. You. Want.
In the same vein as Argus, any damage-y Jinteki deck likes this a lot. It also synergizes stupidly well with Mushin, which is in faction, amazing, and probably already in your deck.
Speaking of Jinteki, what's worse than losing clicks and piles of money to PSI games? Having your other clicks just straight up taken away. No PSI game. Just poof, gone, I'm scoring a Nisei now thanks.
Any time you just want to be a massive jerk. Taking half of the runner's turn away is baller.
It's hard to be a disposable 3/1 agenda in the game of Netrunner, but False Lead more than pulls its weight.
