First, Shipwreck is a new card being released in the Phase 2 of The Early Church. They aren't out yet, but Rob has posted early proofs on Facebook. This particular card negates and discards a site or fortress.
Second, the hand limit at the end of your turn is still 8, but you can never have more that 16 in hand at a time (that was an update).
I don't think that even the speediest of decks should use Tables, IMO. If your purpose is just speed, that is mostly a dead card, and you should be playing stuff out of your hand (characters and such) to be able to get under, while the remainder can be discarded because you won't need every single card every game.
