Ooh, I get to be the first to look this over! OwO

The first thing I would suggest is a better description, to be honest. It's hard to critique something with zero knowledge of its goals. I see you're working on a budget, so I'll tailor my advice accordingly.

As general advice, I would include Beast Within over Bramblecrush, Counterspell over Cancel, Unravel the Aether over Fade into Antiquity, Explore over Urban Evolution.

I would also try to put in a bit more draw that's not dependent on having large creatures (Rhystic Study is pretty sweet).

Bonds of Mortality is trash under most circumstances. I wouldn't normally play it unless I had a very specific reason to do so.

Considering how many creatures you have, have you considered cost reducers like Cloud Key or Semblance Anvil?

You don't have a Sol Ring in here. You should fix that.

Quicksilver Amulet is a great way to cheat things in early and unexpectedly.

Of your maybeboard, I would definitely try and find space for Command Tower, Fierce Empath, Lightning Greaves, Soul of the Harvest, and Temple of the False God. I would cut Manaweft Sliver, Sylvan Scrying, Bonds of Mortality, and Natural Connection.

If you get some more money, Mana Vault and Asceticism would fit well here.

Hope this helped - happy deckbuilding!

Yea, not sure yet on the actual goals yet other than "ha ha blue, stomp stomp stomp". Was thinking a dragon theme/subtheme.

Beast within, Counterspell, Sol Ring, Lightning Greaves, Command Tower, Temple/False God... Kinda the staples I was talking about lol. I do have a Fierce Empath and Soul/Harvest, just wasn't sure where to fit them. I do like the 'Reduced Cost' idea, esp considering it's pretty much'bigthings.dec'

Regarding Fade vs Unravel: Fade is Exile, gone, bye bye, see ya! Sure it's slow, but you can't fetch it again from exile. You could if it was returned to your library though...

Looking pretty good. I also have have a Surrak deck. You might find my list helpful.

Completely Adequate: Surrak Dragonclaw

If you're looking to cheat things into play, Elvish Piper is great, and Quicksilver Amulet is useful in a few ways. Sure, it costs to activate, but it becomes mana fixing in a pinch, and allows you to sneak something out at the end of the last player's turn, providing pseudo-haste. Both the Piper and the Amulet mean the creature can't be countered, either, which is solid if counterspells are a problem for you.

Other 'cheat into play' cards you might not think of in include Call of the Wild and Zoologist. There are some great cards you could run to help set those cards up, like Sylvan Library, Mirri's Guile, Sensei's Divining Top, Soothsaying, and even Scroll Rack. I'm not sure you would want to make that many changes to the deck, but they are a few other thoughts maybe outside the box to think about.

For more cheat Wild Pair though you need to cast the creature but otherwise its nice when you dont have Piper or amulet

If you want to go for big things maybe Savageborn Hydra would be a nice addition. Or if you want to do the dragon theme thingy go for Dragonlord Silumgar always fun to take over something big your opponent has.And maybe a bit more control? Disallow or Voidslime.

Wait I made a mistake, I was thinking about Sultai and not Temur when I suggested Dragonlord Silumgar. I'm sorry.
