It's changed a few times what we put out first.
Though this was one I liked:
Wizard: Azurean Genie, Mana Worm, Sistarran Robes
Beastmaster: Wychwood Faerie, [Enchantment on Mage], Razortusk w/Badger Frenzy
Generally, you want a simple strategy that each player can grasp right out the gate. That's why I'm often a fan of the Satyr Gruff. He has some obvious combos and encourages an aggressive play, which helps get people right into the action.
