If it sounds too good to be true, it's because it is. It's common sense that something like that combo which would break the game isn't a real combo.

We now have Eliza's Toybox which doesn't require any other cards and can do any ICe or Upgrade or Assets like the Root for 3 clicks. Is this breaking the World?

At this point RTFC comes into play. Not that "TGTBT" is at all a good argument, it's as purely subjective as "Rules As Intended," but for that matter, giving the runner a Time Walk to rez one card is hardly TGTBT unless it's a truly obnoxious card, and even then the tradeoff is significant.

I play Oversight AI as a counter....literally.

I pay the the 1 credit, point to the applied ice, put a condition counter on the ice ( a purple glass bead ), place Oversight AI on the side with another glass bead of the same color on it.

After the ice is trashed, I place OSAI in the archives and counters are returned.

I do the same with Parasite and of course Femme.

I use Chess Pieces and keep my Knights and Rooks in my program row. Makes MU easier to remember.
