Two: Azure Drake
Azure Drake might as well be known as old faithful. One of the favourites since the game’s release, with Azure Drake you always know what you’re getting. He’s not overpowered the way that other cards are, but he always packs a punch. Getting a body worth almost four mana, plus drawing a card, is a great value at only five mana. The spellpower bonus is just that, a bonus, icing on an already good card. This card won’t win you too many games by itself, but it will always be a strong play, and a great card to pull off the top when your hand is empty.
Azure Drake’s value comes largely from the card it draws, not from its own body. It doesn’t impact the board and it’s not intimidating, so it doesn’t fit particularly well with very fast decks. However, its value is great enough that nearly any deck that plans to go past turn five will want this guy. He works best with Mage, Rogue, and Druid, as they are the classes that benefit from spellpower the most commonly.
