OK, what links the following banks: IRS, Offshore Banks, Bank of England, Federal Reserve and Savings and Loans? Yes, Criminal Government groups. Violent groups which are also Criminal or Government are just as good since they have loads of power. The Gnomes of Zurich and big powerful groups go together well.
This deck revolves around the above idea, it contains no Corporate cards at all, and apart from its obvious power is designed as an isolationist plot burner and parasite, yet also a deck that can be seriously nasty to both Bavaria and the Servants of Cthulhu. Bavaria is vulnerable to Government power equal to their own, and the Servants of Cthulhu are ideal victims for a couple of spectacular sandbags, so despite the isolationist concept this deck is capable of being immensely destructive (with the right plot cards) and striking fear into all opponents.
The real strength of this deck is it's versatility. It can go with the wind, make use of various opportunities, and of course, being Zurich is never going to be short on power. The weakness is in linking Criminal and Government groups. The IRS and New York are essential, if lost it is very hard to maintain a supportive structure, Manuel Noriega will help but is very vulnerable. You might want to carry the Plots Nationalization and/or Assertiveness Training as added security or carry a duplicate of one or both of these groups.. The only other significant threats are a more effective plot parasite, AKA The Network and another Zurich - both are discussed in more detail later.
Consider what other Illuminati are around, what Plot and Groups Cards are in your hand, and decide on a strategy. If possible then stick to it, but remember, if all else fails a change of plan is possible.
First get a powerful group down fast, New York is the perfect move if possible, or if not, the Federal Reserve, or any Criminal group with a reasonable amount of power. But be careful about putting the Mafia down if the Servants of Cthulhu are present. Let them play it first, it can be taken later.
Use the IRS to tax anyone who looks like they are playing with a lot of violent or government groups, you can always make use of their plots.
Offer to help any of the weaker Illuminati, the UFO's, Discordia and Bermuda for example. They make good allies at this stage and are unlikely to ever be in a position to do you damage. If they are on your side it will stop any real nastiness from more dangerous Illuminati.
Try and get a small compact structure of groups that can support and protect each other easily, and build up the number of plot cards in your hand as quickly as possible.
As to your other intentions, keep them all guessing. Attack other Illuminati only if forced to do so, pick on the big guys if you can - You have enough clout to do serious damage. Hit Bavaria if possible, don't destroy groups, instead take the odd government group off them, or if you don't want the group then help someone else to do it. Saddam Hussein and Savings and Loans really come in useful for hurting Bavaria and there's nothing funnier that seeing them reduced to grovelling for aid.
At this stage, if possible, leave The Servants of Cthulhu well alone. They can be got later. It is better to deal with The Enemy and other more immediate dangers.
The FBI. This group very is bad news, destroy it at the first possible opportunity. Even if you have previously annoyed the Servants of Cthulhu their help is pretty much guaranteed. (Finally petition the Secret Masters for a new plot card - The Second Thing We Do....)
Or be really subtle and start from three groups short of a win, which may appear to everyone else to be even further away. One Automatic takeover, one Privileged Attack, play Blitzkrieg. Lo and behold, you are one group short and have action tokens on all your groups bar one and a fist full of plot cards. Easy isn't it!
And if all else fails, do not forget this is a Gnomes of Zurich power deck so simply bludgeon your enemies to death!
Disasters and Assassinations - If you need 'em, or use the IRS, (or plot cards) to plunder them from your rivals.
Wall Street - Well it is a Bank. But it is Corporate. Try to defend it with Criminal groups, see what I mean, forget it. Oh and forget all those other Corporate groups as well.
Switzerland - Why bother!
Emergency Powers - Goes very well with the above idea.
Up against the Wall - This is sneaky, if the opportunity is right, why should it only be the Servants of Cthulhu who start destroying their own power structure?
The Holy Grail - an excellent addition to the protection of New York.
Agent in Place - another way of messing with an opponents plots.
Logic Bomb - not as effective as The Auditor From Hell but still useful.
George the Janitor - keep messing with plot decks.
Nationalization - an excellent way of making a Criminal group Government as well. Try it on the Mafia!
Assertiveness Training - Another way of supporting Government groups with the Criminal groups (well Violent Criminal groups).
The Pentagon - Bavaria sandbag.
Texas - Bavaria Sandbag.
CIA - Sandbag against anyone playing Violent Government or a useful addition if you want to make the deck more aggressive.
Secret Service - As above.
Phone Phreaks - Network Sandbag.
Post Office - Network Sandbag.
NSA - Network Sandbag. Oh, and it's a Secret group.
