In blackjack does the dealer get the cards in a tie?

I'm not sure what you mean about the dealer getting the cards.

So, a quick lesson in Blackjack. When the dealer and the player both have hands that have the same value it is called a push, no win, no loss. There is no such thing as a tie-breaker. The dealer must stand on a 17 or better and hit on a 16 or under, no exceptions. As for the dealer getting the cards, the dealer gets all the cards, the dealer has control of the cards at all times.
