I think the “magic” in GW for me is the fear it instills.
I mentioned this in the MM Discord chat, but will share here as well.
I went 5 for 5, and didn’t lose a single troop, BUT
It took me nearly an hour to complete those 5 battles!! 
And I loved every heart pounding second of it!
It has been a looooooooooooooong time since, Ive had to think about my moves. Suddenly I was contemplating every match, reading the board, planning cascades, baiting the AI, it was brilliant. GW has brought back the “edge” of early game, where a wrong move can spell defeat. That is lightning in a bottle for me.
Thanks devs!!
