Hey I like the idea here. A few suggestions to hopefully address the issues you mentioned.

Heroic Intervention can help against removal and maybe buy you more time to setup.

Vivien, Monsters' Advocate seems to fit the general theme pretty well.

Search for Glory could help find The Ozolith or Vivien, Monsters' Advocate at opportune times.

As for mill, the only real answers I find we have right now are being able to dig into the graveyard for goodies, just removing all their mill enablers early if possible, 80 card decks, as a way to combat mill, have gotten more popular it seems (just add Yorion, Sky Nomad for the lols if you need to justify 80 cards), but tbh mill is a little OP at the moment if built properly.

Hope this helps and I look forward to seeing the evolution.

All three of those are great suggestions, thanks very much. Some deck searching could help with speed and getting enough creatures out.

80 cards to defend against milling makes a ton of sense. Im usually only a couple turns from making headway, so that extra 20 cards would certainly buy me some time. That's a great suggestion.

I used to have a deck similar to this a few years back so I am trying to build this one at the moment. How do you deal with flying I’m wondering?

Flying is probably my number two downfall after milling.

The only things I can do are the swallow and fight instant/sorcery cards to directly remove them. Or make them use them as blockers if I'm on the offensive.

I'm not sure what I could put in there. Maybe something with flying counters or a card that can spawn cheap flyers? Any suggestions?

hmm. maybe throw a Broken Wings or two in there, or that other instant that gives +1/+3 and reach? i'm blanking on the name right now. I'm excited to try this out though, thanks for posting!

Thanks! I think it's Sudden Spinnerets, that's a good one too. If I have the Ozolith out I could recycle the reach counter too. Thanks for the advice!

Stonecoil Serpent could help against flyers. I'm working on an abzan version of this deck, I felt like the removal in w/g is just a little too weak. I think you'll find that tightening up the list will help with consistency (more 4 copies rather than a bunch of 1 and 2)

Stonecoil Serpent is an excellent suggestion. That would help a lot.

I'll work on getting a more consistent deck, I was initially trying to mostly use what I had available in my collection, but I'll start looking at what to buy/get more copies of.

this deck has been fun! it does have its weaknesses but it is what it is, I threw Yorvo, Lord of Garenbrig in there and he combos really great with Iredescent Hornbeetle and plenty of other cards too.

Awesome! Glad it's working for you. Yorvo does seem like a great fit.
