Editing Yu-Gi-Oh! Trading Card Game (section)

==Formats==
Tournaments are often hosted either by players or by card shops. In addition, [[Konami]], [[Upper Deck Company|Upper Deck]] (now no longer part of ''Yu-Gi-Oh!''{{'s}} organized play), and [[Shonen Jump (magazine)|Shonen Jump]] have all organized numerous tournament systems in their respective areas. These tournaments attract hundreds of players to compete for prizes such as rare promotional cards.

There are two styles of tournament play called "formats"; each format has its own rules and some restrictions on what cards are allowed to be used during events.

The advanced format is used in all sanctioned tournaments (with the exception of certain Pegasus League formats). This format follows all the normal rules of the game, but also places a complete ban on certain cards that are deemed too powerful or are unsuitable for tournament play. These cards are on a special list called the forbidden, or banned list. There are also certain cards that are limited or semi-limited to only being allowed 1 or 2 of those cards in a deck and side deck combined, respectively. This list is updated several times annually and is followed in all tournaments that use this format.<ref>{{cite web|url=http://www.yugioh-card.com/en/limited/|title=Official YuGiOH U.S. Site – "Yugioh Forbidden/Limited Cards: Advanced Format – Limited and Forbidden Lists"|publisher=Yugioh-card.com|access-date=February 22, 2012}}</ref>

Traditional format, created in October 2004, is a format where all cards in the advanced format's forbidden list are instead allowed at 1 copy per deck, while all other rules are identical. This format is rarely used in competitive play.<ref>{{cite web|url=http://www.yugioh-card.com/en/limited/|title=Official YuGiOH: Traditional Format – Limited Lists|publisher=Yugioh-card.com|access-date=February 22, 2012}}</ref>

The game formerly incorporated worldwide rankings, including a rating system called "COSSY" (Konami card game official tournament support system). COSSY was retired on March 23, 2017.<ref>{{Cite web |date=February 27, 2009 |title=YGO TCG News: Konami Unleashes Champion Pack 8 on Duelists Everywhere |url=http://shriektcg.twoday.net/stories/5547423/ |access-date=February 22, 2012 |publisher=Shriektcg.twoday.net}}</ref>

With the introduction of the Battle Pack: Epic Dawn, Konami has announced the introduction of drafting tournaments. This continued with a second set for sealed play: Battle Pack: War Of The Giants in 2013. The third and final Battle Pack, Battle Pack 3: monster League, was released on July 25, 2014.

There is also ''Time Wizard'', a format that relies on the ruleset, card pool and limitations of a specific past date in the trading card game's history.<ref>{{cite web |last1=Quintana |first1=Eric Ortega |title=Konami Made Five New Formats? |url=https://www.cardmarket.com/en/Insight/Articles/Konami-Made-Five-New-Formats |website=Cardmarket Insight |date=3 January 2022 |access-date=4 January 2025}}</ref>
