Admittedly I'm new enough to the game that I haven't played a whole lot with glacier strategies of days past. What my understanding of the glacier strategy is that you want to 1) make stealing agendas out of remotes taxing so they can't just take them at will and 2) make the runs less valuable by ending them prematurely (caprice) or robbing them of accesses (ash).
The second point has become much much harder with the introduction of Political Operative, Councilman, and much more importantly Rumor Mill. The options are to shift to different less effective defensive upgrades (most suggestions are core set cards or relatively old ones at least) or use different strategies to tax the runner enough to blast open a scoring window or facilitate scoring.
These are ideas I can see having some validity (depending on your influence they may be more/less viable).
1) Sea Source, Closed Accounts, Install.
This can be an effective counter to runners who have enough econ to keep pressuring but not enough to beat the trace. Nuke their money and never advance.
Snare, Psychic Field, PriSec. This can be a way to bluff out early runs while not losing tempo. I especially like PriSec because if they want to keep running they have to trash that as well.
3) Fast Advance
I think this is what everyone's been doing with their HB glacier. Score 2 - 5 points the hard way and/or find a way to score the remaining with Biotic, Jeves, or both. I think EoI sorta falls in this column though it's got different moving parts that don't necessarily work with the rest of the fast advance close-out strategy.
4) Rig Descruction?
I really like Aggressive Secretary. Is it worth running here? Will-o is also valid for when the problem cards are Paperclip or Clone Chip instead.
