Just a few cards I really wished existed...
#1 Starport Kaguya (counter for account siphon)
#2 Console for Kit (what about 3 cost, 1 memory, 3c - make a piece of ice a code gate)
#3 Something to help positional ICE (no, tenma line and sunset don't count)
#4 BWBI viability (At the beginning of your turn you may advance a piece of ice without using a click)
#5 Nerf for Astroscript (make a run on a remote server, if successful remove an agenda counter)
There are other things I'd like, but I think we really need #1 and #5, and the rest would introduce a lot of now useless cards back into the meta.
