First Time Building a Deck: Orzhov Knights (Modern, Kitchen Table) - Need Help!

Hi everyone! This is my first time building a deck, and I’ve decided to create an Orzhov Knights deck for kitchen table games. It’s in Modern format, and I’ve tried to give it a ‘bloody’ artwork theme.

Here's my current decklist (deck tech in description):

Some points I’d love feedback on:

• Does the deck have a clear strategy, or should I focus on a specific synergy?
• Are there any budget-friendly upgrades I could consider?
• Am I running enough lands/mana?

I’m new to Magic: The Gathering (3 months) and open to all kinds of advice. Thanks so much for taking the time to help!"
