If duelbook or similar simulators have a written play by play that could be referenced after the fact for writing purposes,  that might help,  but still seems like more effort than my proposed system,  particularly since my method can function even if you only have time to go through a single turn. 

My system does have a slight stumbling block of "what if you go through a whole turn only for the other player to have a response to everything before they can even take their own turn", but at that point it's a matter of coordination between the players,  making both ideas kind of a hassle in the same ways that matter,  so maybe just roleplaying it is the better (or at least simpler) option?

I'd like everyone's input on this, seriously: simulate it,  or just roleplay it (for the love of gods, just vote for one; "I'll just go with whatever" is completely unhelpful)

Collaboration posts using a public writing pad site is usually how I've done things. Whole duel in one post. Granted that's also usually in RPs with discords or other forms of active immediate communication being utilized so that players can discuss as rhey are adding to the duel.
