Turn 3 Druid of the Flame and turn 4 this = 2/8 or 5/5. Similar to 5/5 +4 health Priest Mech card but comes one turn earlier, which could be important. It's really hard for some deck to remove 2/5 Druid of the Flame or even Jungle Panther, which will become a 4/6. Pretty good I think.
Another good beast synergy card for Druid, but that's all it is; good.
Druid needs only one OP beast card to build its deck around, like what Gadgetzan Auctioneer used to for miracle rogue. This card hasn't been printed yet, but once it is, Druid would have plenty of good beasts to support it.
