Beast druid with The Curator. Pretty standard stuff.
Basically, this deck is Beast druid. It plays exactly like every other Beast druid deck out there; however, The Curator can potentially draw up to 3 cards when played.
Generally, this deck starts out with a strong early game, then curves out into the midgame with a combination of spells and minions before ending the game with cards like Savage Roar and Menagerie Warden.
Mulligan hard for your 1-2 drop minions and Living Roots/Power of the Wild.
TLDR, Beast Druid with The Curator.
EDIT: Sir Finley can be replaced with a Coldlight Oracle if card draw is insufficent.
