Deck idea

Just a Druid deck that tries to use Sylvan Splendor, Assorted Animals, Unlikely Alliance and Mother Nature to maximum effect:

Spellbook

Almost all minions are Beasts, so Sylvan Splendor draws at least a card each turn, and Assorted Animals can fetch every minion you need.
50+ cards are minions, so that Mother Nature almost never misses to summon a minion.
Unlikely Alliance: 21 Ordinaries, 21 Exceptionals, 9 Elites and 4 Uniques (Mother Nature, White Hart, Tawny, Bruin) make it likely that you draw at least 2, most likely three, sometimes four cards.
Squeakers, Pigs of the Sounder, Grand Old Boar package, for fun.

Atlas

Pond is an auto-include in Beast decks. Aqueduct, Lighthouse, Fertile Earth, Rivers and Blooms make it so that you hit your thresholds, Bog and Impenetrable Copse prevent early loss to aggro and projectiles.
