The era of non-duplicate decks, or Highlander decks, has returned with the re-introduction of the league of explorers. This time, Brann Bronzebeard is presented in the form of Dinotamer Brann, who can summon King Krush in case you have no duplicates in your deck.
The other card in this deck that requires no duplicates is Zephrys, a new legendary that uses AI to help you win the game, or stay alive in dire situations, as it were.
The rest of the deck consists of the usual suspects, such as Subject 9, Zilliax, and Zul'Jin. Such a line-up will definitely help win you games against both aggro and control players.
