[@Crimson Flame]You would have a lot to catch up on, but luckily it is mostly easy to learn. 

RP duels I figured would be handled like usual, and probably just be a few discussions between individuals to see how they would like to handle everything, winners, losers, etc. Individuals could either know what their hand is going to be (for lack of a better term stacking a deck) or there are deck shufflers to get a bit more of an authentic experience. Just so long as everyone is having fun and can come to an agreement.

If there is enough drive for something else, like us doing the duels on DuelingBook (as they have custom card creation and usage) then we can always handle it there, but the prior method is generally used a lot more, and I've only seen a couple of instances where its become an issue, Most of those were due to a lack of communication or just a general dick of a player.

Edit: A bit of a poor explanation, but its just discussing with different individuals about how everything will be handled.
