As much as I loath yugioh arc-V, I may be interested in joining an RP about it. In the last few yugioh RPs I've been in I've used a RNG-based scripted format for dueling, where draws and other random events are decided by a simple number generator. Sure you have to trust your opponent not to lie, but I like to think they will be honest about not drawing all five pieces of exodia as their starting hand. Are you entirely against custom cards in this RP? I can send you the latest version of Cybell's deck, the character I originally created back for your last yugioh RP if you want to see how her Alchemy dragons are looking today.
