Need help tuning my Edgar Markov deck for high power / bracket 4

Hey everyone,

I’m planning to build a high-power / bracket 4 Edgar Markov deck and would love some input from players experienced with tuning Edgar for fast and resilient gameplay.

Here’s the link to my current card pool — these are all the cards I already own and can use for the deck:

What I’d like to know:

• Is it realistically possible to build a high-power / bracket 4 Edgar deck with the cards I currently have?
• Which cards should I cut, and which are the highest-impact upgrades?
• Which key cards am I still missing to reach the high-power threshold? (tutors, interaction, stax pieces, fast mana, specific vampires, etc.)
• Any must-have buys you’d recommend to push the deck to its limit while keeping the Vampire synergy strong?

My goal is a fast, proactive list with strong advantage, efficient tutoring, solid interaction, and enough power to keep up with other high-power decks.

Any suggestions are appreciated — cuts, additions, evaluations, or full list ideas. Thanks in advance!

TL;DR:

I want to build a high-power / bracket 4 version. Looking for advice on what to cut, what to add, and which cards are worth buying to push the deck to competitive levels.
