The 2/4 and taunt reminds me of the echo bells card for paladin, and 4 mana for 2 minions isnst the worst, have too agree that outside wild fandral comobo this card wont see any constructed play. Though as an arena card, it seem pretty good
So, for 4 mana you either get to summon two Bloodfen Raptor or apply a buff similar to Velen's Chosen? That doesn't sound half bad to me considering some sort of aggressive Deathrattle/Token/Egg Druid.
Token druid might run one of these. You can make some really beefy boards after a spreading plague/whisps/violet teacher sticks. If you can't get a board it's not even totally dead because you can throw down some raptors to trade.
It'll be a card that allows token druid to keep being a thing after branching and spreading plague leave, because there will still be whisps, violet teacher, soul of the forrest.
