- The Arena is a great way to gain expert cards if you do not have the money to buy a lot of packs. One Arena entry costs 150 gold and it guarantees you at least one expert pack as a reward. If you win seven matches in a single run, you will get your gold back and enter a new Arena.
- At the beginning of the game you do not have too many cards in your collection to play with them. The Arena gives you the opportunity to play with every card available in the game and by doing this you will know what kind of cards do you want in the future.
- Playing the Arena teaches you how to build a deck. In Constructive Mode is very important to have a well-balanced deck and which cards it must contain. The Arena teaches you about the value of the Mana Curve in a deck and the value of every single card.
- The Arena helps you discover the synergies between you, the cards and each faction. It will help you find out what is your favorite hero to play or which cards are perfect for you.
- The Arcane Dust is a valuable resource in the game because it helps you to craft the cards you want. There are only two options to gain it: as a reward from the Arena or by disenchanting expert cards. Disenchanting cards is a dangerous method, especially for the beginners, and it gives you a small amount of Arcane Dust.
- Arena Mode can be a great way to gain gold too. In other modes, such as Ranked or Casual Play, you will be given ten gold for each three victories. That means you will have to win 30 matches before you can buy an expert pack. In the Arena after you reach four or five wins, all the gold you will get as a reward can be considered a bonus.
- Finally, by playing the Arena your strategy skills will improve. You will learn how to adapt to unexpected plays, how to control the board, when is the right time to play a card and when is not.
