Sorry - I didn't see that there was a response to this deck till now.
To remove:
I prefer direct draw over tutoring, so that's a handful of cards that I personally would take out.
Icon of Ancestry = 3 mana maybe draw a card. Not good enough.
Herald's Horn = 1 mana creature cast reduction and maybe draw a card per turn...Not so much an elf tribal card as it is huge non-green tribes that don't have card draw and need the mana reduction.
You can always take out some lands and replace them with 1 drop mana dorks. Better ramp, and can draw off them.
Asceticism - The regen will only affect your commander himself as his regen will cover all your other creatures (and cheaper), and you probably won't be leaving a ton of mana unspent. Is hexproof really going to win / cost you games? If so - how?
Talara's Batallion - Is this just a pet card? I fail to see its value. 4/3 for 2 mana isn't relevant value in commander...with a commander that pumps all your creatures +3/+3 per 5 mana spent.
Gempalm Strider - it seems like the exact thing that makes this card ok, your commander already gives you. You could say it's redundancy if you lose your commander, but it's only +2 without trample and can't be repeated no matter how much mana you have available.

For the Eldraine cards:
Keeper of Fables - isn't an elf, so it wouldn't even occur to me to include it in an elf deck. On its own - it seems good, but cards that require you to attack for value (Druid's Repository,
Overwhelming Instinct) are worse than face value because often you're in a position where you don't meet the requirements (having creatures that can attack), are in a position where attacking will lose you your board (bigger enemies), leaves you open to counter-attacks, and some - like this one - require you to connect with the player (so you can't even do planeswalker control). In a deck like this in particular where you can pump + give trample, you should be swinging for lethal anyway, so the card draw is too late to matter.
Oakhame Adversary - It's an elf with deathtouch already that justifies a roster spot. I couldn't really criticize someone for wanting to include it right there. If your motivation for inclusion is the card draw, then I think you've stumbled into a good decision despite poor judgement.
The Great Henge - Given it's cost, I get the sense that players everywhere must be overrating this card. It's a great card, and it should be included in most decks - but I get the sense that there's hype around it like it's one of the best cards in green.
Return Of The Wildspeaker - I look at this as being a third
Rishkar's Expertise &
Soul's Majesty (fourth if you include
Garruk, Primal Hunter). Great card in big creature decks, but here you want many cheap elves. If you're thinking about pumping them, then using this...well you've spent your mana so...why? Why mix a 'card draw turn' and a 'pump attack turn' in reverse order? Ever? Card draw -> pump, not usually the other way around. If you start with pump, do more pump. I did buy like 20 of this card though, as it has a place in almost any green deck with medium to big creatures. The other option is fine too if you're running a deck with a bunch of over run effects, but you're not doing that here because - EZURI.
Castle Garenbrig - I see almost no possible use for this land. You can get an extra mana out of it (creatures only) which is a huge problem and it won't benefit from cards like
Vernal Bloom,
Gauntlet Of Power,
Keeper Of Progenitus, or
Nissa Who Shakes The World. Also can't be fetched by
Kodama's Reach /
Cultivate /
Skyshroud Claim / etc. The benefit it gives you to include in the deck (if you're not running those doubler's above) is comparable to starting each game with a free 0/1
plant token. Sure take the value.
