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).
