The invention herein describes a card handling apparatus used for automatically creating play-ready hands for use in casino poker games whereupon the apparatus may be programmed to accommodate a number of different game variations, and a variable number of players. The apparatus verifies the integrity of each deck before discharging the play-ready hands to a first discharge portal. Decks that do not meet verification criteria are isolated and moved to a second discharge portal. Non-faulty decks are moved to a metering station where they are metered to a card output tray at high speed while forming the play-ready substacks. Two decks may be shuffled, verified and queued within the device before commencing a game, or a second deck may undergo shuffling while play-ready hands from a first deck are being metered to the output tray.
