Perhaps spells take several turn to resolve on the board or even have multi stage resolutions before they dissipate (like how sagas work in mtg). I do think part of the fun of the mtg stack is the speed of it.

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.
