The other reviews are pretty comprehensive, but something that's been left out -- SanSan City Grid is a powerful FA tool for Regenesis decks. With one preinstalled, you can score Regenesis from hand, letting you concentrate on protecting Archives rather than awkwardly trying to defend both Archives and a Regenesis on the table. It's vulnerable to Clot and the instant-speed sabotage tricks mentioned in other reviews, (and it requires a lot of money) but it's very powerful out of Jinteki: Restoring Humanity which can easily make enough money to fund it.
