Need deck help

I like entering combat alot I feel it gives you alot of control in the game. I'm still a novice tho and I'm not sure how to go about this. My brain tells me blood sorcery and potence cards added are what I'm thinking so far

For new players it's generally recommended to play with established decks not dedicated to combat. So Blood Sorcery combat is a worst choice.

Maybe stick just with potence? Not so good either, but IMO eurobrujah is a quite fine beginner deck.

I have been playing magic for 10+ years of that makes a difference

Yeah, not sure why you'd play Hunter's Mark and Potence. Feels overkill, since Potence with Immortal Grapple does not have much use for HM and, if you have Blood Sorcery and Celerity I wonder why you'd need Potence in your combat: Banu Haqim using Hunger of Marduk with additional strikes will be deadlier.

So, maybe please be more precise: do you want a Banu Haqim rush deck? A potence combat/rush deck (without using Hunter's Mark)? Any kind of efficient combat/control rush deck no matter the disciplines? Or is it really the core idea to use both Hunter's Mark and Potence and why?
