The powerlevel of this card may just be a little over the top, but maybe thats exactly what Glacier needs.

1 rez, 5 trash is comparable to e.g. Jeeves Model Bioroids, which as well can (combined with other cards and actions) result in some serious tempo gain and thus often is a must trash. It's an asset though.

Combined with the already powerful Ultraviolet Clearance and Violet Level Clearance , Jinja City Grid allows for clickless install of all the ice you draw, on up to 4 ice deep servers for free. This card is not unique so you can install one in HQ, R&D and your remote. This way abusing the clearances becomes possible for all (HB-) factions, not just Cerebral Imaging: Infinite Frontiers.

Long story short, in combination with massive card draw effects Jinja City Grid is a huuge boost to Glacier style decks. These decks excel in taxing runners out. Add in a little Bryan Stinson, who really pushes those clearances over the top and you got yourself a tier 1 Glacier deck.

Runners beware you will have to deal with not only horizontal but also vertical spam in the near future (looking at you Anarch).

This will create some out of control servers. 5 ICE deep servers for free. A savings of 9 credits after factoring Jinja's rez cost. And since the credits aren't recurring credits, you can do this very fast. The price of course is giving the runner full knowledge of the ICE installed. —
Full knowledge means nothing when the tax is real. This out of ASA (with tons of upgrades as I've been playing it) will be tough to deal with. —

This is probably one of my favourite consoles.

Most consoles you want to have out as early as possible because they give , , on runs, virus tokens or even card draw.

This means you would run 2x or even 3x a console which can be installed only once.

The fact that Brain Chip is essentially a late game console makes it such a nice one of in all those decks that don't rely on an early console with the above features, thus saving deck slots and possibly some influence.
