How do conflicts work in YOUR games?

So I’m getting back into MG because it’s the best system out there (I just need people to play it with me). Reading the 2e rules I got to wondering: When in a conflict, especially a fight, who comes first for you: The action “card” or the narrative? Do you select actions based on particular movements or techniques or equipment you would like to use? Or do you select actions with the intention of narrating the conflict once the opposing actions have been declared?
In other words, do you narrate first, THEN lay down your action? Or do you prefer to let the cards dictate the action?
No right or wrong answers here, just looking for some ideas and insights!

For us, the cards come first and the narration is adapted to fit.
