Here is how this works you can make a challenge(as any Yu-Gi-Oh character) as an open challenge or to a specific member(as any Yu-Gi-Oh character) of their choice. You may set up rules to the duel like use your deck or their deck. Example of a Open challenge
"I Yugi Moto challenge Seto Kaiba to a duel" ( character decks)
Now this would mean whoever except this challenge will use a blue eyes deck vs a spell caster deck that includes Dark Magician. you may make any challenge you like in different ways but you must duel and the in game chatter will be in character.If you have an in duel issue please contact me or another admin here with the ruling issue at hand and we will assist and after the role play will continue.

Wow all these roleplays.
