Tournaments are finally making a comeback next year! You might have heard that there are already two in-person Yu-Gi-Oh Championship Events scheduled for 2022, and remote duel regional qualifiers are also kicking off this month. There are significantly more opportunities for players to engage in large events over the next five months. If you're feeling a bit rusty with your rulings, or if you've never participated in an event beyond your local official tournament stores, this article will help you avoid simple mistakes that could land you with a game loss!

Yu-Gi-Oh tournament policy is designed to create fair, competitive, and enjoyable experiences for all players. Naturally, enforcing fair play sometimes means serving penalties against duelists for various reasons. A game loss is a type penalty that's deployed by judges in response to infractions, and it's exactly what it sounds like: you'll automatically lose one game of a match.  

Dropping a game in a match for a non-gameplay reason can be devastating, although not impossible to come back from. Game losses are far from the biggest penalty that you can be served — a match loss is often the next step against more severe infractions — but they're easily avoidable, and should be avoided whenever possible.

#1 Procedural Errors

There are a lot of moving pieces in Yu-Gi-Oh, and as cards and strategies become more complex, there are more things to keep track of. Mandatory effects, maintenance costs, once-per-turn activation restrictions, and time-sensitive effects all need to be independently tracked and strictly adhered to. Missing an optional trigger effect is one thing, but missing a mandatory effect or Life Point payment, or failing to resolve a card completely or correctly, is a much bigger issue.

Procedural errors largely emerge from simple mistakes. Maybe you draw a card in your Draw Phase after resolving Reckless Greed the previous turn. Or perhaps your opponent doesn't pay 700 Life Points during their Standby Phase while they control Imperial Order. Procedural errors are rarely intentional, but the problem is that there's no way to differentiate between an intentional or unintentional error. Beyond the prospect of cheating, players are expected to maintain consistent gameplay by following the rules of the game at all times. 'Forgetting' or choosing not to resolve an effect, even if that effect would benefit the player, disrupts the consistency of the game and negatively impacts the competitive experience.

Because procedural errors can creep into anyone's gameplay, and because complexity is always increasing in modern Yu-Gi-Oh, avoiding a game loss to a procedural error is more challenging than other infractions. Still, there are a few things you can do that will help you better keep track of game actions. Practicing with a particular deck, especially against someone who knows the deck better than you, is a great way to make sure you're catching any errors in your plays early on. One of the worst things you can do is play a deck for the first time at a regional or YCS event.

Another way to avoid procedural errors is to regularly re-read your cards. No, seriously, just read them from time to time. Everyone who plays this game has the capacity to confuse card effects, make assumptions, or even just forget about a restriction on a particular card. When some cards have four or six sentences it's easy to make a mistake, or to assume a card works a certain way because that's how you've played it in your recent duels. This isn't as much of an issue for a deck you play regularly, but it's definitely a problem when people pick up a deck they haven't played in a while.

#2 Being Late To A Match

Tardiness infractions occur whenever a play isn't ready to play three minutes after the start of the round. If you've played enough in-person events, you've probably had the experience of scoring a match win off of your opponent simply not showing up after ten minutes. This usually happens when a player leaves the tournament but doesn't confirm that they've dropped from the event. Game losses occur after the three minute mark, while match losses require a full ten minutes. At smaller events, and particularly remote duels, avoiding a tardiness infraction is relatively easy. That changes at larger events where players might need to leave the venue between rounds to buy food. It's an even bigger issue if your matches tend to go long, which leaves you with very little time to find a snack!

Bringing some kind of food with you to an event is a great way to keep yourself energized during the day. Anything that's easy to eat and snack on without making a mess — and won't fall apart in a backpack or bag — will help you avoid making a run for food when you're pressed for time.  I've traded a game loss for Taco Bell at a regional in the past and didn't regret it, but that's not exactly a winning strategy. Bring food, team up with friends to make food runs, and don't go to an event already hungry if you can avoid it.

#3 Deck List Errors

It can't be stressed enough just how important your official deck list is. The list you submit needs to be error-free, and consistent with your actual deck. Failing these checks could result in a penalty, including a game loss, match loss, or being dropped from the event if you can't produce a legal deck. Game losses occur regularly if your deck list is illegal, your actual deck is illegal, or if there's a mismatch between your deck list or deck that cannot be corrected before the first round.

Careful preparation is the best way to avoid deck and deck list errors. Lock in your build and card choices before the day of the event, and don't rely on picking up specific cards to finish your build. Every extra variable you insert into your deck building process increases your chances of making a mistake. Write your deck list before the event, and only make changes if you absolutely must. Konami provides online deck list forms and a guide on how to appropriately fill them out right on their website. If you're filling out a form by hand, make sure you completely spell out the names of your cards, or double check to make sure your abbreviations can't lead to confusion about the cards you're playing.

#4 Marked Cards

Marked cards and sleeves are another common source of warnings, but they can become game losses or even match losses in major cases. Marked cards or sleeves have some sort of distinguishable feature about them that allows players to identify a specific card even while face-down. This can include a dent, crease, tear, or dirt that somehow makes a specific card easier to single out. In the past, duelists have been disqualified for indenting their fingernail into their opponent's cards to identify them for later. Marked cards are usually unintentional and fixable without a game loss, but you can easily avoid both.

Take the time before an event to either re-sleeve your deck or double check that all of your sleeves are in good condition. Make sure you're buying sleeves that actually fit Yu-Gi-Oh cards: oversized sleeves allow cards to shift in the sleeve. Double sleeving is a relatively new addition to the TCG, so it's worth noting that marking can exist on both the inner and outer sleeves.  Make sure all of your inner sleeves are the same brand and pattern. Check your sleeves regularly throughout the tournament. If a sleeve is damaged during a round, replace it. Keeping an extra set of sleeves on you is a great way to avoid making a surprise run to a vendor. Lastly, try to avoid mixing different batches of sleeves. Even the same brand and product can have noticeable differences between packages.

#5 Unsporting Conduct

At the end of the day Yu-Gi-Oh is just a game, and it's important that we all leave negative emotions and egos at the door. Unsporting conduct infractions help Konami remain a healthy tournament space where players feel invited to have fun competing against their fellow duelists. Personally, I'm never upset with the outcome of a duel as long as my opponent is being reasonably respectful. I've had a lot of great experiences enjoying games even at top tables against players that genuinely enjoy playing Yu-Gi-Oh, and I'd never want my opponents to have a bad experience playing against me. I'm still trying to win, of course, and sometimes that might mean activating Mystic Mine.

Luckily, unsporting conduct isn't something you'll have called against you just because you're playing an annoying deck. Most minor cases that result in a warning are the result of non-duel actions.  For example, a player placing their food or drink on the table, insulting another player, failing to follow the instructions of tournament officials, or being unhygienic. (Yes, you can actually receive a warning for smelling bad!) Like other infractions, unsporting conduct penalties can be upgraded if necessary. By default, game losses are appropriate if profanity is used towards another player, if a player refuses to sign or rips up a match results slip, or if the duelist becomes violent towards property — like a chair — after losing.

I probably don't need to give advice about how to avoid insulting other players or throwing chairs when you lose, and I assume most of us understand that taking a shower and using deodorant are the most effective ways to avoid a hygiene warning. There are some lesser-known instances where repeat warnings could eventually upgrade a warning into a game loss. Video recording, violating a buying/selling policy at a venue, or even making unfair trades with less experienced players can all lead to unsporting conduct infractions. It's worth reading the entire list on page 27 of the Penalty Guidelines.

There's one more infraction category that I didn't cover: drawing additional cards.  There's no real suggestion to make here so I went ahead and skipped it, but just keep in mind that you can get a game loss if you're especially reckless about drawing and adding cards to your hand.

One of the best resources for any duelist participating at a tournament, whether they're totally new to the scene or a returning player, are the judges themselves. Judges can answer questions about rulings and card legality, as well as specific questions about sleeves, apparel, or store policy. Not sure if the questionably proportioned Dark Magician Girl on your playmat is acceptable? Try asking a judge before you roll it out in front of your round 1 opponent. 

Ultimately, it's up to you to keep up to date and stay in compliance with tournament policy. Don't simply take other players at their word when they talk to you about policy. The best way to avoid infractions is to read the documents yourself and clarify with a judge if you have any questions.
