It's decent, but need some cards to combo with it. 

Could be good discovered by renew or palm reading. 

It's okay, given it's just a peon.

Seems very strong! Now we need a minion with battlecry "your next hero power deals one more damage."

Pyroblast to all enemies, can't underrestimate that power. 10 cost is very expensive though, so will probably only be played in control mage.

Such a fun design. I won't want to play agains this card. 

8 cost is very expensive, although the battlecry is impressive. Can see this viable in druid, but only druid maybe.

Looks very flexible! But 4 cost is a bit awkward for some classes. E.g. Mage can't put fireballs in their deck, druid can't overgrowth, and no sword eater for Warrior! Rogue, on the other hand, will have no trouble using this card. Value rogue maybe?

Could be really good in shuffle rogue, if rogue has a way to tutor the 3/10 out by turn 4.

It's actually not that bad, if the opponent has nothing on the board this is 5 damage to the face. Also 6 health is tricky to deal with.

If Shaman gets decent card draw next expansion, spell damage aggro shaman could be strong. 

Not so good to include in decks, but good to discover from renew/palm reading when you just need that bit extra healing

Speaking of new cosmetics, some pet-themed cosmetics like the guardian from LoR would be cool.

Hope this will keep pirate warrior alive in standard after the rotation.

It's very versatile, but I'd much prefer this to be a 3 drop or 4 drop. 5 drop is a bit too expensive for its effect. 

Glad the powerful DQA will be back!

Not Sylvanas...my disappointment is immeasurable and my day is ruined.

Good luck everyone. I'm hyped for the coming expansion.
