i don't disagree with you, but is this card the one that fits into that vein?
like what about Code Siphon needed to be a run on HQ instead of R&D just because 'it's boring for all of the faction cards to be the same server'
Code Siphon is a mediocre card that needs to be fixed in some way for it to see any use, but what you've done is not only change to server target, you've increased the tag penalty, you've added an additional effect. it still fetches a program, but the cost reduction effect is also quite different. at this point, it's not a card renovation, it's just an entirely new card altogether.
i think what you've done is go in the opposite direction and simply remake Account Siphon with green effects and green border
i also disagree that Anarch works just as much on all servers. sure, Medium and Nerve Agent allow amazing multi-access, but only insomuch as it fits with Anarch's colour pie of dismantling corp servers and then hitting them when they're vulnerable. Medium doesn't really work if the corp ICEs up R&D too much for the runner to reliably get in enough to make repeated runs on a single turn, so ICE destruction is one of the primary enablers of getting it to work (i know lots of stuff has changed since the core to make Medium way more oppressive, and i won't dispute that at all, but at its core, Medium is a very Anarch thing, despite being currently the best R&D digging tool available)
Sneakdoor Beta is a run on archives, but it's still pressure for HQ
i don't think Code Siphon fits into 'it shouldn't be a run on R&D because it's boring'
i think Code Siphon doesn't see play, not because it's just another run event on R&D, but because it's generally a bad effect for the costs involved. simply changing it to HQ doesn't fix that, but if you do fix the effect, does it really justify switching servers now?
