How many Spider cards are there in HearthStone?

I know of three:

• Haunted Creeper
• Tomb Spider
• Ball of Spiders

Are there any more?

Solution 1:

• Anub'ar Ambusher
• Anub'arak
• Ball of Spiders
• Haunted Creeper
• Maexxna
• Nerub'ar Weblord
• Nerubian (Coming from a Nerubian Egg, Anub'arak or Ambush)
• Spider Tank (Not really a spider, but it has the form of one)
• Tomb Spider
• Webspinner

In addition there are two uncollectible cards. Spectral Spider which spawns from Haunted Creeper listed above, and Spider which spawns from Infested Wolf (from the recently released "Whispers of the Old Gods" expansion). This makes for a total of 12.
