It’s Wild Growth and 2 mana for a card draw at the very least.
Druid should be able to survive a turn like that.

It’s a 1 mana 2/4.

Some decks would run a 1 mana draw 1.
Free 3 healing. The fact that it heals enemy face isn’t relevant for any priest deck except Shadow. The fact that it heals enemy minions is not that relevant because it’s a 1 mana card, you’ll have plenty of mana left to set the board to your best possible hand.

It’s not just control though.
Any midrange deck could run this. Some extra healing and a free trade to beat other midrange or aggro seems pretty good.

“You can’t roll the same keyword twice – if you get e.g. Taunt once, it will no longer be in the pool. Of course, +2/+2 is an exception – you can get it multiple times.”

In the cards description 😀

Should see some play in Priest imo

‘Destroy a minion’ spells count as an honorable kill, yes!

If you play this on turn 3 while trading of your previous 2 cost minion, it’s kind of a 2/6 taunt.
Your opponent can’t really leave it on the board and 6 dmg is a decent amount to deal with 3/4 mana.

Wild combo:
Cards required: Zombie Chow / Embrace the Shadow or Auchenai Phantasm / Grave Rune / Spiritsinger Umbra / Deliverance / Emperor Thaurissan

Obviously reduce your 5 card combo with Emperor Thaurissan .

Play Spiritsinger Umbra for 3 mana
Play Auchenai Phantasm for 1 mana
Play Zombie Chow for free and deal 5 dmg
Play Grave Rune for 3 mana on the Zombie Chow
Play Deliverance for 2 mana on the Zombie Chow dealing 5 dmg and summoning 3 new ones dealing 15 dmg.

9 mana / 5 cards / 25 dmg
You could use Circle of Healing to kill three more Zombie Chows for a 40 dmg combo.

Won’t win you many games, but might be a fun combo to try out. 🙂

I think Hunter is a class that can easily make it work though. Rapid Fire, Wound Prey, Springpaw, …

Plenty of 1 mana – 1 damage cards in Wild to manipulate an enemy minions health.
You shouldn’t have a lot of issues with getting the effect trigger at least once.
