This idea that over multiple turns you both are building up to something and then in 1 turn there's this huge fight that exists only during the combat step or end step and once it all resolves you go back to your normal speed. It's exhilarating.

I feel my above example of breaking the stack down makes the spell slinging more like spell slogging. Also how do resources work? Is it mana based? Something else? Card drawing? Traps? Auras? It could also be interesting to have multiple win cons.
