The casino gets this edge primarily because the player goes first. The player has a chance to bust before the dealer. Basic blackjack multi-deck strategy is designed to minimize the house edge. Card counting is the next step beyond basic strategy. Card counting seeks to take advantage of knowing when there are more ten value cards in the shoe.
