Hey @misused
I'll preface this by saying: Great work! The amount of progress you've made in the short time we've had is pretty incredible.
I've tested out your configs with good results, those to be expected in these nascent stages. I have this to say:
I think the use of Blackwald Pixie should be considered. Its a 3 mana 3/4 that has the battlecry "refresh your hero power".
If used on turn 7, you can use your hero power twice, enabling 6 damage to face.
If you have a beast on board, the addition of Kill Command can make it 11 damage.
With 11 damage at 10 mana, this makes the Blackwald pixie + Kill Command combo even more powerful than Pyroblast, albeit the longer setup.
Blackwald Pixie would have to be mulligan-ed out in every scenario, since before turn 7 it is practically useless. It can act as a late game finisher, however, along with Leeroy.

To substitute into your deck, I propose you take out Bittertide hydra. This will most likely be an aggro meta, and as such, this card will be more of a hindrance than benefit.
The Odd Hunter relies mainly on smaller minions, such as Woldrifer (3/1 charge) to burst down the opponent.
All in all, great work. I hope you'll become legends like Scott and Botwhat in the future!
I'm looking forward to your new updates :D
