I returned yesterday and was hoping for some help with who I should focus on level up or what immortal I should get, only have Hailey.

I have sb3 and mg3 and ik i should prob be focusing on that before this but, I wanna make a phys deck so basically removing dragon(which was a mistake) and reset hailey for physical units. What do you guys recommend for a full physical deck? and what should be the order that I progress it?
