I'm not sure you're getting any milage out of Ironbeak Owl. Direhorn is bad without Curator or N'Zoth. The big wolf thing is probably better. I think you only want 1 Pixie (if any) to use as an end game finisher. I would probably consider double reckless Flurry, since at worst Hero Power + Flurry is a 5-mana, 4 damage AOE. I get what Jones is doing here, but teching in theory craft seems ambitious.
This is a silence meta, and silence will still be highly relevant in witchwood because cubes are (probably) going to be so strong and therefore prevalent. I put 2x Direhorn in my odd warrior too. Being able to armor up for double throughout the game makes getting to fatigue hugely more consistent and viable, and in those cases, getting to fatigue 2 turns later while also having large overstatted stuff available when you do get near the end of your deck is excellent. I can see the rest of your points though.
My first theorycraft about witcwood, share your opinions!
