So let's talk about Mumba Temple... The only real problem is the 15 ICE number. It should've been more like 12, or 10.
Mumba Temple is a powerful Asset at 1 to rez, 3 to trash, and giving two recurring credits, but only to be used for rezzing cards.
- 1 to rez 3 to trash indicates a card that does not immediately pay out for the Corp, but pays out over time. (PAD Campaign is similar.)
- Because it gives out more credits than it took to rez it, the limitation on what you can use those credits for is an important factor in the card's power. Realize: To get value from this card, you must be Installing Things.
- Because ICE are how you protect servers, and you could potentially use Temple to rez ICE much more easily, the limit on how many ICE in your deck was designed to put a cap on how effective that use case could be.
The problem(s) with Temple only appear in decks that are built specifically around Temple. I would argue that you can see these same problems in decks built specifically around almost any powerful card, like Clone Chip, Parasite, Sifr, Account Siphon, Accelerated Diagnostics, Boom, 24/7, Astroscript Pilot Program, Biotic Labor, Jeeves, Ash, Caprice, Batty, Hard-Hitting News, Sensies Actor Union or Blue Sun.
Is Temple a good card? Undeniably. Is it a broken card? Well that depends...
- Is it seeing play across all Corp factions? (No; Afaik, there isn't an HB Temples deck. It does see play across the other three, so that's a point against it.)
- Is it going into every deck without concern for the gameplan of the deck? (Definitely not. Mumba Temple only appears in decks that have a significant number of Assets.)
- Does it immediately change the game state in one player's favor? (Arguable; The card by itself does nothing, but it does set up an economic advantage over several turns. Compare/Contrast: Sansan City Grid, Account Siphon.)
But anyway. This topic isn't really about Mumba Temple. It's about whether we should do something to cap the number of remote servers a Corp can make.
If anything I think there should be Runner cards that deal with it, I sorta like the three proposed, but honestly I think if we got a slightly-buffed Scrubber that might do it.
