1. Question

A player preparing for a Regional tournament was told by a judge that submitting an incorrect deck list through Yu-Gi-Oh! NEURON could result in a penalty for cheating.

The player had instead completed a physical paper deck list and believed the paper version should take priority because it was filled out at the event. Their paper list contained the correct deck, while the NEURON list was potentially incorrect.

The question was essentially: Which deck list submission method takes priority, and what happens if a player submits the wrong list or fails to submit one?

2. Reddit Discussion

The discussion emphasized that players should follow the instructions given by the Tournament Organizer (TO) for the particular event.

If the TO requires deck lists to be submitted through NEURON, players should use NEURON. If the TO requires a physical paper deck list, players should submit the paper version instead. If a player has a legitimate reason why they cannot use the required method, the issue should be raised with the TO before the tournament.

The discussion also distinguished between different types of tournament infractions.

A Procedural Error — Minor was described as a minor gameplay mistake that can be corrected, rather than an incorrect deck list automatically being classified as cheating.

The Judge & Moderator responding to the question identified incorrect deck-list information as potentially falling under Deck Error, with the discussion distinguishing between:

• Deck Error — Minor: Warning
• Deck Error — Major: Game Loss

The discussion also stressed that cheating requires intentional misconduct. An accidental or uninformed deck-list mistake is not automatically the same thing as intentionally cheating.

However, intentionally failing to submit a required deck list can potentially be treated much more seriously. The Judge & Moderator noted that the exact infraction could depend on the circumstances, while another commenter stated that playing without submitting the required list can result in disqualification.

3. Summary of the Reddit Answer

Situation	Reddit Discussion
TO requires NEURON	Submit the deck list through NEURON
TO requires paper	Submit the physical deck list
Player has a legitimate reason they cannot use the required method	Discuss it with the TO before the event
Deck list contains an accidental error	May be handled as a Deck Error
Minor Deck Error	Warning
Major Deck Error	Game Loss
Player intentionally falsifies information for an advantage	Can fall under cheating and potentially result in Disqualification
Player intentionally does not submit a required deck list	Serious tournament issue; exact penalty may depend on circumstances

4. Conclusion

The main lesson from the Reddit discussion is that the Tournament Organizer’s instructions determine how the deck list should be submitted. A player should not assume that a paper list automatically overrides NEURON, or vice versa. If the event requires a particular submission method, that method should be followed.

An incorrect deck list also should not automatically be described as cheating. The discussion distinguishes accidental deck-list errors from intentional rule-breaking. Deck-list mistakes can fall under Deck Error, with the severity determining the penalty.

Most importantly, players should make sure their submitted deck list accurately represents the deck they are playing before the tournament begins. If there is a problem with the required submission method, it is better to resolve it with the Tournament Organizer before playing rather than assuming another form of submission will take priority.
