Alright, it's 1 AM over here and I like sleeping. Quick recap on the consensus so far that I think we've managed to reach (correct me if I'm wrong and point out if I missed something):

-Setting is a 5D's esque dystopian Satellite knockoff
-People start out with tablescrap decks
-No point buy system/card pack progression system. Just ask the GM if you want to change your deck up in any way.
-Duels are done in whatever way the two players that do it agree to do it in. Just no simulators.

I'll also throw out some thoughts to keep the discussion going while I'm asleep:

-If we're going with the 5D's knockoff, what's the crowd's thoughts on Turbo duels? Personally I'd like to throw them in, though not every character would need to be a turbo duelist. If they [i]are[/i] thrown in, do we do it with or without speed spells? I'd probably allow some custom speed spells, if only because the current selection is pretty limited even if we take all the real-cards-turned-speedspell-variant from the games.

-Duel gang seems to be an idea that gained some favor, so how about I set you guys up with the following: Outside antagonists and general NPC's, I'll have one GMPC that'll act as the leader of a duel gang which all your guys' characters have rallied under one way or another. What the objective is for the gang isn't quite clear yet (would need ideas if you guys are cool with it), but either way they'll be clashing with rival gangs for territory and with security because law enforcement. Y'all cool with that or would you rather something else?

If I'm having a shit idea again, feel free to call me out on it.
