I played several games againsta a deathrattle hunter with this deck and won like all of them. You have to manage your resources; Supercolliders + Shield Slams deal with Cubes and Kathrena, and the Ironbeak Owl is the MVP. Also, Azalina copying a hand full of Zombeasts is a game-winner.

I don’t think so; I added Azalina and an Eternium Rover to replace them. You could also try like Rotten Applebaum or Wargear for mech synergy.

After the nerfs are finally live, what to sub for the Gigglings? Would Rottlen Applebaums do the job? Or maybe Arcane Keysmiths or a second Tyrant and one of the previously mentioned cards? What do you think?

My opinion:
Giggling Inventor: I personally think the card didn’t need a nerf. Well, it was a neutral rare, so anyone could play it and there were good counters aka Mossy Horror. At least I can still run a single copy in my Odd Warrior.
Mana Wyrm: What have it done to them!!!??? Tempo Mage is basically dead; it wasn’t even a Tier 1 deck. Mana Addict is a much better option now I think.
Aviana: The only fair nerf here; at least Wild wouldn’t be such cancer. +1 from me.
Other: Well, I don’t see Spreading Plague or Branching Paths here; I also think Healing Rain should be nerfed to 4 or even 5 mana, but it’s just me.

THIS. IS. THE. WORST. HERO. EVER.

Seems pretty legit, but I don’t have Rexxar and Snake Trap. Can I replace them?

Of course, assuming you 1) cut Corpsetakers, 2) already craft Al’Akir, as he it definitely the one to craft first here.

Well… I’ve made this deck a few days ago – without Kalimos, but with Hagatha. It did’t really hurt me to not have Kalimos, but Hagatha is a game-winner against control and controlish-midrange decks such as Odd Warrior or Even Warlock. I would definitely craft her first; also, Kalimos goes out in the next rotation.

You could add MCT (Mind Control Tech), Flappy Bird (Vicious Fledgling), also Exodia.
