The Temple of Orsis
Personally, I used Dragon Priest to clear the whole 1st wing. After playing, I recommend the following below.Zinaar
Normal: Draw a card. Give your opponent a Wish.Heroic: Draw a card. Gain a Mana Crystal. Give your opponent a Wish.
For normal, I guess you can clear with any class. You will have an easy time with Priest, Rogue, Mage and Mill Druid. My son even cleared it with Face Hunter.
For Heroic, I will recommend Flamewaker/Mana Wyrm Spell Mage and Mill Rogue.
Recommended Class: Normal (any class), Heroic (Mage, Rogue, Druid)
Recommended Cards: Flamewaker, Mana Wyrm, Frostbolt, Mirror Image, Ice Lance, Fireball, Flamecannon.
