Rulings at the World Championship

Over the years, the OCG and TCG have become rather different card games with the release of OCG exclusives and TCG exclusives. However, the main defining factor would be the difference in rulings.

Here are some of the different OCG and TCG rulings observed in past, and how they were ruled in each of the respective World Championship.

  • OCG ruling for Necro Gardna:
    Necro Gardna’s effect can be chained to the activation of an effect that removes it (i.e. D.D. Crow).

Conclusion

As seen from the past few World Championships, as well as the upcoming one, the OCG ruling has always been favored, no matter where the World Championship was held at. Nonetheless, it is comforting to know that the rulings were revised and standardized eventually.

In the past, difference in rulings were often attributed to two separate companies handling the game, namely Konami Digital Entertainment and Upper Deck Entertainment.

This is still true currently.

Although Konami Digital Entertainment, Inc has taken over all Operational and Business Aspects of Yu-Gi-Oh! TCG, it is still a different company from Konami Digital Entertainment Co., Ltd.

Konami Corporation is made up of multiple subsidiaries (separate legal entities), namely:
Konami Digital Entertainment Co., Ltd. (Japan)
Konami Digital Entertainment, Inc. (America)
Konami Digital Entertainment GmbH. (Europe)
Konami Digital Entertainment Limited. (Asia)

Unlike divisions in the same company, subsidiaries operate on their own, and in a sense, are competitors in the global market. As Konami Digital Entertainment Co., Ltd. (Japan) and Konami Digital Entertainment, Inc. (America) are separate entities, they have their own R&D, which sometimes produce different rulings.

Ideally it is in everyone’s best interest that both companies collaborate and standardize their rulings, but it is simply not feasible in real life.

Even in Japan itself, as each set is Tournament Legal upon their release, a temporary ruling is often issued through the Rulings Hotline in the early few weeks. It is not uncommon for said temporary ruling to be revised when the Official Rulings are released later in a month’s time.

To remain competitive, it is optimal that you educate yourself with the correct OCG/TCG ruling observed in your region. Avoid confusing yourself with the other OCG/TCG rulings. For the uninitiated, Duelist Codex covers only OCG rulings.

    this sorta pisses me off cuz i hate ocg even more ever since the ude dispute
    sigh……..whatever it’s worlds who cares about this event

      really? it’s TCG that changes the rules and TCG exclusive that make games imbalance in the first place. The different in rulings in time of UDE it’s because the translation error of the text’s card but now it’s not, it’s because TCG wants to sell more cards (yeah I’m talking about u, Tengu)
      OCG never trolling on its player base, at least not as TCG. in OCG we have CCV at 1 dollar, DAD at 2 dollars. Card games are meant to play by everyone not by the elite or veteran players. It’s times for TCG to change.

      by the way, Worlds are meant to be a bridge that make OCG and TCG the same thing, which what it’s differ should only be promo cards pool (which will be the same in months after anyway) not by rulings difference. It’s time they settle this once and for all

        the ruling gives ocg players an advantage and i like tcg meta it has skillful players that win because they play conservatively can’t say so for ocg but i guess players differ upon surroundings. veteran players not only exist in tcg but ocg as well.
        i love that tcg has exclusives cuz ocg gets everything before us so how can you say we would be the same without them. the meta is very different too tcg players like consistency over explosive plays, but they can balance both those out and make a monstorous deck like tele dad. true ocg kinda decides tcg’s future {synchro cat, samurais} barring the impact of exclusives and what has an impact there has a bigger impact here like synchro cat and samurais. card’s prices are marketing and that’s what this game is truly about, you don’t just get cards like they did in the show
        and for the world’s thing world’s always get herp derp decks so idk about the sskill factor there and the ocg ruling puts tcg player’s at a disadvantage cz priority is a big thing here

          Which is why it’s hilarious that we have a different rules in the same game? Why TCG didn’t change the rules after it was announce it’s out of my wit. Surely, card can’t play itself, veteran players are still veteran players but due to easy access of cards, it open more opportunities for all player to build a good deck. Which in essence is the difference in marketing plan. OCG ways are after sometimes they will reprint good cards so all can play the game competitively. TCG has many good exclusives and they’ll available in OCG in some packs as well and TCG has its own way to gain TCG exclusive as well so I didn’t care much about card pools but what I concern is Tengu (and more or less, Tour guide) the card is strong BUT when the “official” rules of exceed are out (from OCG) and by that rulings Tengu and some combo (tour guide + sangan) can’t be used so TCG decide to go “hey don’t believe ocg” and has its judge post in “Facebook” how Xyz mechanics are in TCG ways. Surely, they just want to change the rules to accommodate their creation and saying “Hey, that’s different wording but results are the same” and “Worlds use a “special” rules but in reality it use OCG ones” TCG tendency to use their own rules make all these things happen, not OCG

          meta is different? Plants, samurai, hero beat, gadget, GK, Agent Angel, Anti-Meta. not so much differences if u ask me. Well x sabers will be one of the meta here since the release of dark soul in ocg. and Agent will be in TCG meta as well since the release of structure deck so, no much difference.

              when i mean the meta’s are different i mean the card choices and the way the decks are played so for example in ocg i’ve come across agent builds using perfect herald but in tcg i’ve never seen one, it all comes down to consistency i believe, and in tcg tengu tourguide plants, name says all it’s not doppel junk and debris or something which is horribly inconsistent, 4 cards target the grave! ocg is lucky gravekeepers aren’t as big there as it is here and with at least 2 mained veilers i really don’t know how doppel even exists, guess it’s the ocg explosiveness right? you are right about the ruling though they did announce it but to be honest konami sucks i actually liked ude and the relationship they had with the players.
              for the tourguide thing with the new ruling on exceeds i think tourguide is hands down better then tengu
              and tcg gets all these special rulings and priveliges cuz we’re awesome
              thanks for replying

              oh yeah and that’s a lie i’m still pissed we never got the sixth sense trap card!

    Tewart needs to just go by the OCG, instead of the western branch of KDE doing its own thing.

    Just a nitpick but Worlds 2010 was in Long Beach, USA I believe
