Seems fun

+1 from me

Sandwurm Convergence would be on theme and probably good

+1 from me I like the deck

+1 from me I like the deck

Some possible changes I would suggest:
- Your in Naya colors so why not run 1 or 2 of Samut? I do understand that this is modern and your trying to keep the curve lower but she seems so fun in these colors :)
- If this isn't budget Tireless Tracker would be good
- I would play all 4 Thraben Inspectors

+1 from me I like the deck

All I would suggest is:
+2 lands
and maybe finding some more card draw to put in

uh...

Regal Caracal?

lol

+1 from me though like the deck

I just think Aether Poisoner is just straight up better than Dhund Operative because the bonus power Dhund gets doesn't really matter with deathtouch
You also seem to have a side energy theme going here and Aether poisoner supports that

Also adding +2 Gonti, Lord of Luxury would be pretty sweet because he is card advantage which I feel this deck needs a bit of, he also has deathtouch, and he is budget

+1 from me always like a well constructed budget deck

+1 from me

I love Eldrazi

+1 from me I like the deck

I usually run 24 lands in my decks and a lot of people make arguments for 26 in control decks since you wanna hit your land drops
Even with the curve being lower I would still at least go up 3 lands at least

+1 from me I like the deck:

I assume by "first deck" you mean your new to the game so welcome

Aside from the tips Anon88 already gave you the only other thing I tell new players is:
Don't forget/underestimate card draw
- "Draw a card" are the best three words in magic
- For your deck I would suggest 4 Read the Bones but really any card draw spell you have available would be fine

Yup,
Scions by themselves aren't the best way to ramp but Cryptolith Rite makes them a bit better

+1 from me looks fun

Only thing I'd do is +2 lands

+1 fro my me Eldrazi are my favorite and I love the deck:

1. I don't see the point in running so man ingest cards without a lot of payoff for exiling the cards
2. Scions and ingest are 2 different types of Eldrazi decks usually
3. You've got 61 cards in the deck (try and get it to 60)
4. Also I'd add +2 lands for sure

I have a scion ramp deck on my account that's proably my second best deck I own so if you want some ideas you could look at that

I agree with #2: because 4 mana counters aren't always reliable
I don't know if your building this deck on a budget but if your not then running all 4 disallow would be good

I don't agree with #1 though: many control players (including pros) run only the 4 gearhulk espeacilly with so many ways to dig for them

Some changes I'd personally make:
-2 lands (I easily get by with 24 I have control decks)
+2 Baral (he'd be pretty awesome)
-1 summary dismissal (maybe sideboard it?)
-1 pull from tommorow (3 seems to many)
+2 disallow or censor

+1 from me overall I love the deck

I actually personally prefer harvester as a card more than heart because it can block heart and gain you life.
That might just be me.

+1 from me I like the deck

It isn't quiet standard though:
Standard right now is the battle for Zendikar block, the shadows over innistrad block, the Kaladesh block, and the amonket block.

Also I'd go +2 lands for sure

+1 for the cool deck

Not exactly what I'd call budget though :)

+1 from me I like it

Looks like you have a "collected company" deck going here. Check up the card and if you like it use 4.
Other than that you've titled the deck a "tamiyo" deck and it does perfectly fit her colors so maybe a full 4 copies of her?

+1 from me

I have a mono blue counterspell deck on my account - similar to this deck.

Sorry last thing :)

This is a Sphinx's Tutelage deck so for sure you need t run the full 4 copies to make sure you find one at least once per game.

Also I didn't see this till now - 16 lands for sure won't work I run 24 usually
