When I first saw this card, I saw potential, I saw a deck, one that I wanted to build and I wanted to play.
I'd tried to make a Mumbad City Grid Grail Ice Deck before it was even released, I've been trying until I started writing this. Sure there have been plenty of games where this has turned a server with little more than a Galahad and two junk ice into a 15 subroutine unbreakable monstrosity, and given a Komainu more subroutines than the runner had cards left in their deck.
But it was too slow, Parasites and Cutlery were running rampant. The ice I needed for that beautiful remote server was needed to seal the holes that kept forming over R&D, achieving the installation of the 3+ ice needed to make the remote was nigh on impossible.
Just as I was starting to feel that the deck was tuned well enough to be able to cope with it, and as Dumblefork took a huge hit from the new most wanted list...
A card that is far easier to satisfy, has a much more potent effect, renders parasites little more than a tickle, and costs nothing to rez was released.
Sandburg essentially does everything this ever wanted to do, only far more easily, and far more effectively.
My deck has run faster and more effective since I tore out it's still beating heart, and replaced it with cold, hard, unloving cash.
But it's not the deck I wanted to build...
It's not the deck I wanted to play...
It's not my deck anymore...
Mumbad City Grid was never quite fast enough to properly reach it's potential, and now... it probably never will be.
