Hearthpwn

With ONIK comes beast druid, a before less than viable deck that struggled with early game and lost to aggressive opponents, now with the addition of Enchanted Raven and Pantry Spider, the deck is capable of contesting for the early game and keeping enough presence on board, whilst also taking advantage of crowd buffs with minions that split themselves in two.

This deck is fairly new so I really can't offer much in terms of mulligan except to always mulligan for Raven and other early game minions.

Addled Grizzly, despite seeing no play after its release, is a questionable pick, but I feel it works as a proactive Power of the Wild that features a 2/2 body to accompany it. I think this is a viable pick, at least as a one-of, thanks to cards like Mire Keeper and Pantry Spider, who get double the benefit from the effect.
