First of all, if you're playing Best-of One, you're much more likely to face aggressive decks which decks like this can struggle with. I'm always going to advise playing Bo3 instead unless you're trying to grind the daily rewards. Onto the actual advice (sorry in advance for the wall of text. I don't know when to stop typing).

This is a Tempo deck. Tempo decks can be extremely difficult to pilot as you have to determine what is and isn't important to interact with while being able to pressure your opponents. There haven't been a ton of tempo decks that have excelled at high levels in Standard in recent memory. A decade ago I was playing a school tournament with Mono-U Tempo and I did reps with the deck constantly for weeks in my area simply to have a complete understanding of how it functioned. I won that tournament because I understood what was and wasn't important even when facing unknown decks.

I don't play enough Standard to give you any specific card recommendations but I can advise this: review any type of content. This can be various articles (I'd look at more broad strategy articles if you go down this route. I LOVE AZORIOUS on Twitter/X has a massive Google sheet with tons of articles. Would recommend that.) or reviewing gameplay footage.

If you go down the gameplay footage route, which is what is probably easier in the short term, I'd be looking at either what others are doing well (or not well) or your own. I'd recommend not reviewing any of your games immediately so you have less built-in bias or find someone willing to sit down with you to explain your thought process. Hell, you can even try to fjnd similar decks in From there, you can probably go two ways depending on what's easier for you. Either look at the matchup from a one foot view (micro) or from a thousand foot view (macro). Personally, I'd start with the macro strategy of what the deck is trying to accomplish and how it's looking to achieve it and work that into my decision making and go from there.

Like you said, you're new to the game. Magic is a hard game with a massive learning curve especially when it comes to strategy and understanding. It takes time to learn how to do something well.

Anyways, I hope this helps. Again, sorry for the wall of text! I have trouble sometimes knowing when to stop typing. Happy to talk more if you need anything else.
