This may be my favorite card to come out since Blue Sun. It is very niche, but it's niche in exactly the way the best tech cards are niche - small but essential effects that indirectly win you the game by dismantling your opponent's winning strategy - and, more importantly, it's ALL the tech cards at once.
Playing against Fast Advance? Forfeit an agenda to go get your Clot or Clone Chip midway through their installation.
Playing against some kind of murder deck? Forfeit the agenda you just unhappily stole off them to go get your Plascrete Carapace.
Just face-planted into a Destroyer because your SMCs were tied up with getting your rig gowing? Forfeit an agenda and return the favor to that Archer, or just get a new breaker and keep going past Ichi like it wasn't even there.
More to the point, it stretches out all your tech cards. These days, Shapers want Plascrete Carapaces for 24/7 News Cycle, Film Critics for Midseason Replacements and The Future Perfect, Deus X for that random person who keeps bringing Personal Evolution to every tournament, New Angeles City Hall if you're that person, a cheap fracter for Wraparound, etc. There's just not enough deck slots to fit all these in so you can have them at the exact moment you need them more than anything, and leaning on your existing search tools (i.e. Self-Modifying Code) produces an externality chess players call an "overworked piece" - when your Queen is protecting both your Knight and your Rook, you're bound to end up losing one when she has to save the other. Artist Colony just softly pats you on the head, says, "it's okay, we all make mistakes," and gets you back into a game you otherwise would have lost.
"But if you haven't scored any agendas, it doesn't help," you tell me. Let's face it, for one, if you can't score any agendas, odds are good either you're already locked out of the game or your opponent isn't getting substantially closer to winning and you don't really need a tech card instantly, so this isn't the card for you.
But for me, who enjoys playing Aesop-based decks that already can use 0-cost assets as "Easy Marks," it's a vital card that never feels totally bad. And it's only been two weeks, and I've already lost track of the number of games I won solely because I had Artist Colony to save me from the blowout.
