All of that sounds good, but if I were to make a suggestion, it would be to have pvp duels be done in some dueling program, like Duelingbook, if it's supposed to be an actual duel. On the one hand, this allows for a legit duel to happen, meaning luck plays a large part and there's no fudging of the game. On the other, it'd be tougher to write the duel if you know how it happened from beginning to end, unless you write as the duel goes on. Another thing to factor in would be if the opponents are collabing or writing post by post for a duel, since that could influence whether using a program is a good idea or not. And if nothing else, like King Cosmos said, a program would at least shuffle the deck for us and let us know what our hand and field are at a given time.
But since it's less "regular" dueling, I don't know how effective that would be.
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)
