As crappy as this is, Here you go.

Use this card at your turn to rollback any series of actions in the game, up to the the first action.
Combined with the card "dark pool", this card also allows you to add secretely to your hand up to 100 decks of 60 cards that you can play all at the same time.
Oh man. In this crash and rollback mess, I completely forgot about other complaints about Mt. Gox, such as dark-pools-that-aren't-really-dark-but-are-merely-convenient-ways-for-mtgox-to-help-big-traders-fuck-over-little-ones.
That's the full feature name, right? Oh crap, I also forgot about websockets crapping its pants during key times. Damn. I think this whole flash crash business was just a rouse to make us forget about the many, many other reasons why we love to pick on Mt. Gox.
