The idea is to trigger a wild chain of Bonds/Debts/Loans/Ventures etc.
All you need are cards for Credit Default Swap, Subprime Mortgage, and Mortgage-Backed Security, and you can play Dominion: 2008 US Banking Collapse Edition.
Subprime Mortgage - Action/Reserve $0
When you play this, put it on your tavern mat.
At the beginning of each turn, put a fraud counter on this and get +3 cards, +3 actions.
At the end of your turn, unless you have $1 left over for each fraud counter on this, return this to the supply, put your deck and your hand in your discard pile, and trash 12 VP from it (or as much as you can).
Mortgage-Backed Security - Action/Reserve $6
When you play this, put it on your tavern mat.
At the beginning of your turn, +$1 for each fraud counter on each subprime mortgage on other players' tavern mats.
Whenever another player defaults on a subprime mortgage, you gain the victory cards they would have trashed, return this to the supply, put your deck into your discard pile, and trash treasure totalling $X where X is the total VP of the cards they would have trashed. If multiple players have Mortgage-Backed Securities on their tavern mats, the victory cards are handed out round-robin starting with the player to the defaulter's left.
Credit Default Swap - Action/Duration $3
While this is in play, if a player defaults on a Subprime Mortgage (returns it to the supply), gain 4 gold.
At the beginning of your turn, return this to the supply.
