Main Story PvP must take place on some kind of online Duleing platform(Duel Masters, Duel Links, ect.) Record your out come loser makes their response post Must story must remain as an active chance scenario meaning if you win/lose you must proceed accordingly. Multiple mains story-line threads may exist at once but must adhere to lore

Meta-Decks(an online deck recipe known for high win rates) are reserved for NPC's only NO exceptions (This does not pertain to casual duels obviously.)

Side story may use the in house nontcgpvp system "IF THEY CHOSE." Side Story lines get to play it a bit more fast an lose as they're far more interested in story the game play.
