Really? Is this REALLY what Netrunner needs?

Let's break it down. Mumbad City Hall is a stupidly, stupidly powerful card. It propels the Assetspam decks into an obscene powerlevel, has a frankly stupid interaction with Heritage Committee, and is more efficient than drawing and installing.

And now, for 2, , you can play ANY OPERATION IN YOUR DECK! Just by having this as a one-of in your deck and a City Hall on the table. This is madness. We already had an Asset toolbox more efficient than God himself, and now we have an Operation toolbox as well?

Think about it. Always having your Current online. Always having cash when you need it. Always being able to Interns back a clutch ICE that was trashed. Having a consistent Midseason threat. Always being able to find your random, one-off tech cards like Closed Accounts, Snatch and Grab or Power Shutdown. It's absurd. It's mad. It's terrifying.

So what happens now? Now that the corp essentially can play with over half their deck in their hands, and gets to pick and choose whatever they like? Is this good for the game?

Maybe I'm just being hyperbolic. Maybe I'm seeing ghosts where none exist. I really hope it is so, because of this is as powerful as it seems, I fear for us all.

Can this and interns work together? The "paying all costs" section makes me think this wouldn't work with doubles unless you had another click for whatever reason. —
One click for MCH, second click goes to double cost for CV, third click goes to double cost for Interns. It's a full-turn play, unless you are also rocking Jeeves. —
How would it work with Mumbad City Hall and Jeeves? If I MCH a Consulting Visit, am I spending 2 clicks on the same action or not? —
No. You spent 1 cilck on MCH, and 2 clicks playing operations. —
Play Subliminal Messaging before to trigger Jeeves —
How about this: Weyland deck with a single copy of Consulting Visit, three copies of Mumbad City Hall and a single Localized production line? With a full tag and bag suite of course! —
I am rather new to the game, if i look a double click operation with this card, would i spend a total of 3 or 4 clicks? So for example using this card to look up witness tampering i would spend 2 cloci —

New technology destroys the old.

The time for rotation has come, and with that, it's time to say goodbye old friend.

The Professor is a teacher. He taught me a great many things about Netrunner.

The Professor taught me the true extent of what a Shaper toolbox can do, by pushing the limits of what you could put in it. He taught me the limitations and strengths of Shaper in general. He taught me how to tune decks like no runner before him, thanks to his unique influence setup. He allows you infinite options for exploring new ideas, even as he forces you to evaluate every card you put in his curiculum.

No, The Professor will never turn any metas on their heads. He will never be the most powerful thing, featured on DotW for winning Nationals. He doesn't exist for the power players. He exists for the dreamers, the ones who want to try things rarely tried before. He exists for the underdogs, the ones who find satisfaction in taking bad cards and making them work, against all odds. He exists for the hopeful hearts, and creates inspiration in anyone who looks at the ID for the first time. And that's valuable.

I hope The Professor won't fall into the wastebasket of history. Maybe NISEI will let him enter the Hacker Hall of Fame, or give him a retrain in some fashion. Maybe he will find a place among the juggernauts of Eternal, though I doubt it. Or maybe he will simply grace the kitchen tables of fools like me who will struggle to let him go.

Rotation may take you out of Standard, but the lessons you taught me will not.

I am interested in trying him out again, especially post MWL. Exile is the worst ID in my opinion though. Even if you build a deck specifically for him with all the heap installs (and there aren't all that many), Kate is a better choice every time. —
Try it out. It's amazing once you get to know how to play with him. —
I have been playing professor before the MWL and i have found him very useful and an amazing Toolbox style of deck. With so many ways to tutor for other programs at your disposal having the right programs can make any game very one sided. —

What is the appeal of this card?

Let's get the obvious bad parts of this card out of the way: yes, the Runner can trash this card and ALL the assets you've put on it for 5. That means, worst case scenario, the runner can trash four clicks and a bunch of credits worth of assets for cheap. So how do we stop this? By making it not cheap.

The payoff you get is twofold: first of all, you get your assets cheaper. This can be huge for economy assets like Adonis and Eve Campaign, more disruptive elements like Hostile Infrastructure and Elizabeth Mills, and even pure value like Public Support. In this game of ours, cash is king, and Worlds Plaza can set up an asset economy fast and cheap.

Secondly, you can defend your asset economy with a single row of ICE. This is the big apeal of the card, as the problem with Asset economies has always been that the runner can trash your stuff and you can never have enough ICE to protect them suffieiently while also scoring agendas. Worlds Plaza solves that problem by allowing you to make a four-deep server protecting your valuable assets.

I think Worlds Plaza is an undeniably powerful card that may put Asset economies back on the map outside of Jinteki: Replicating Perfection. Powerful enough to, even at 5 influence, splash out of faction. It enables you to create an asset economy without fear of #Imp, by ICEing up your assets, as well as protecting all of them with a single Ash 2X3ZB9CY or Marcus Batty.

Try the card in a glacier deck. You won't be dissapointed.

Does the runner access the hosted assets? —
As far as i know, yes. I believe there was a ruling at some point that said the runner could access the ice on Awakening Center, but I can't find it now. This would imply that you can access the cards on Worlds Plaza. —
Might be interesting in combination with off the grid in a super jank glacier :D —
What happens in combination with Blue Sun? Is the rez cost still lowered or can you bounce things back for full? —
Say you had 4 assets hosted on World's Plaza, and one of them is Hostile Infrastructure. When the Plaza gets trashed, does the runner take 5 net damage? —
They take 1 net damage as the runner specifically is trashing 1 asset; 'the game' trashes the cards installed on WP when it dies. Note you also can't host 4 assets on Worlds Plaza... —
Could you use a Cerebral Overwriter or some other trap to protect the other 2 assets? —
You can try, but it would be installed rez, and they can just access/trash the Worlds Plaza to avoid accessing it. —
Is there a ruling yet if the Runner has to access the Assets hosted on Worlds Plaza yet... as normally the Runner has to access ALL cards in the server? —
The Runner has to access all cards in a server, so yes, unless they trash Worlds Plaza, they will have to access everything hosted on it. Remember, though, the runner chooses the order of accesses. Also remember, everything hosted on it is rezzed, and as such it's very hard to make the runner access/trick the runner into accessing anything with it they don't want to. —
@unitled If the runner could access cards hosted on Worlds Plaza I think they would be subject to the same rules, which means the runner accesses ALL cards when they hit the server. I wish we could get a clarification on the rules for this card, I can see two completely different uses depending on the interaction. If the runner cannot access cards (installed on worlds plaza not server) it serves as a good place to host Executive cards while denying the runner a chance to grab free points. If the runner does access cards hosted, it's a good place to put something like Cerebral Overwriter and two Public support, forcing the runner to choose between damage to the face or letting the corp score. —
@TheWackyWombat You can access cards hosted on Worlds Plaza, this is pretty clear. The issue is that while you have to access all cards in a server, you pick the order you access them in. If you access the Worlds Plaza first, you can trash it, and anything hosted on it is instantly trashed. If you put an Executive and an Overwriter on it, you can access the executive, trash and steal, then access and trash the Worlds Plaza to destroy the Overwriter before you access. —
I'd put three Hostile Infrastuctures on it. —
I have the same question GrimOsenia has. The way I read it, Blue Sun would be able to bounce a card back to HQ for full credits. Unlike Breaker Bay which has a constant effect on cards in the same server, this card seems to lower the rez cost on install then its ability is done. —
Can you use tech startup to install directly to worlds plaza? Or do you need to use worlds plaza's effect to install to it? —
Things can only be hosted by abilities that specifically host them or in ways specified by cards. So, no, you cannot tech startup something onto worlds plaza. —
Can we mention the interaction with another Weyland card ? Like Surat City Grid for example... Can be a big economic boost —

Note: You CAN actually Tech Startup on to this card, same with Full Immersion RecStudio. It would be installed face-down (without the discount on rez). The click ability does not, in any way, restricts its hosting ability.

I stand corrected. >From NISEI Comprehensive Rules Document (version 1.4), 1.12.5.b If a card has an ability describing cards it can host, but also one or more abilities that can create host relationships onto itself, then it only allows cards to become hosted on it through those abilities. A card cannot be installed directly onto the card through an unrelated install effect. Example: Glenn Station reads, “Glenn Station can host a single card”, but also has a paid ability that hosts a card on itself. Therefore, Glenn Station only lets the Corp host cards through that paid ability, not through an install action.

So, after about a dozen times of looking at this card, I realized something insane: this card is not Unique.

That means that when you have two or even three out, you get Legwork every time the Corp scores. With HQ Interface, you could conceivably access the entire hand. This is sick against Glacier, as Agendas will stock up in there in anticipation of a scoring window. It is also great against FA as it can help you even the race for 7 through hand pressure.

What seemed to be a cool, fringe effect may turn out to be a real force to be reckoned with, and may even contest Legwork as lategame HQ pressure.

Multiple Gang Signs do not equal to Legwork - you will access one card, return it, then access again. —
Multiple Gang Signs plus a HQ Interface will mean two double-accesses. Yes, you might hit the same cards twice, but that is still some serious HQ Pressure. —
Also, splashing this in Edward Kim means if you draw an Operation with the first Gang Sign, you can trash it so you don't access it the second time. ;) —
Or just Imp with anyone or Whizzard for assets/upgrades. Gang Signs & Imp are each 3 Influence, though, so it's a costly combo no matter who you run it in. —
