Anyone thought about what banlist to use, or is this more of a "Free for all, but don't break the game" kinda thing? I think I'd prefer it as such, because this is by no means a competitive environment, so using a banlist catered towards it isn't ideal.

Yeah I'm scrapping the banlist for this one. I can just veto you if I think you're doing something in bad faith (like putting 5 banned cards in your deck and they happen to be pot of greed, harpy's feather duster, graceful charity, sixth sense and self-destruct button)

Also, I've not seen enough 5ds to know this, do characters use different decks for Speed Duels and normal duels, or do they just use a speed duel version of their regular deck?

Pretty much just a mod of their original deck. Since spell cards can't be used, they swap out their spells for speed spells.

[s]also speed duels are something else entirely, that's duel links format guys please stop calling them that[/s]
