I think its the best to do handwriting duels via pm, then post the results here once the entire thing is done (if you decide to handwrite instead of ygopro etc)
Also, Emily's deck isnt designed for battle really, but it somehow works... so theres that going for me.

Also, YgoPro has got an option called "Use Obsolete rules" which brings back the draw first turn, 1 field spell etc.
And i dislike Duelingnetwork, the manual thingy is kinda hard to work with/feels awkward imo
