New Player, Kardur goad deck deck help

I recently upgraded the Kardur Goad precon on a budget and this is where the deck is at right now:

I'd love to get some feedback on the list. What cards would you cut, and what would you add?

I'm mainly interested in:

• Budget-friendly upgrades that would noticeably improve the deck.
• A few higher-budget cards that are worth saving up for if they make a big impact.
• Feedback on the mana base — do I have enough lands and ramp, or am I likely to run into consistency issues?

If you've played Kardur before, I'd also love to hear about any cards that overperformed or underperformed for you.

Thanks in advance!
