Official Tournament Rules

Deck Registration

  • Players must preregister one 75 card Eternal main deck and a sideboard of up to 15 cards. Decks must be legal for Eternal ranked play:
    • No more than four copies of a single card may be included between main deck and sideboard.
    • You deck must meet Eternal power restrictions (minimum 1/3rd power, maximum 2/3rds power).
    • Minimum deck size is 75 cards, maximum deck size is 150 cards.
      • While your main deck may be more than 75 cards, your maximum sideboard size is 15 cards. This must be true after sideboarding – eg, if you register an 80 card deck and a 15 card sideboard, you may not have a 75 card deck after sideboarding. However, if you register an 80 card deck and a 10 card sideboard, you may end up taking cards out of your main deck and put them into your sideboard resulting in a 75 card deck.
    • Decks must be built on EternalWarcry, and be of the type Tournament in order to ensure both privacy and integrity.

Card Legality

Cards become legal for tournament play a certain number of days after they are released, depending on the size of the release. This is to allow players to reasonably acquire the cards they need for the tournament. If a card is not legal for tournament play, you may not include it in your tournament deck. The general guidelines are as follows:

  • Promo releases are legal once it is possible to have acquired a playset of them. This is usually four days after they are released.
  • Purchasable expansions are legal for tournament play 3 days after release.
  • Large set releases are legal for tournament play at the Organizers discretion.


Individual matches are played in challenge games between the two players. As there is no way to force Play / Draw, games are to be played as they lie when the challenge happens.

You must play your main deck as registered for the first game of every match. After the first game of a Best of 3 series or second game in a Best of 5 series, both players may take time to exchange cards between their main deck and sideboard. Your deck must adhere to all previously mentioned deck construction rules after sideboarding.

All matches in the Swiss portion of Weekly Tournaments and LCQs are Best of 3 Series. The Top 8 are Best of 5 Series.

For Invitationals and other Single or Double Elimination events, the Finals (including Winner Bracket, Lower Bracket, and Grand Finals) will be a Best of 5 Series. Specific rules for these events should be clarified by the event’s official ruleset, if available.


  • Players may sideboard between games after game 1 in a Best of 3 Series
  • Players may sideboard between games after game 2 in a Best of 5 Series

Tournament Format

  • Checking in: Players who have registered for the event must check-in on the Battlefy page for the tournament in the 30 minutes before the event, or they will be considered not to be attending and dropped from the event. Players who are not checked in may not play in the tournament.
  • Pairings will be announced via a Battlefy bracket by the Tournament Organizer.
  • Rounds: The tournament organizer will publicly announce the start and end times of the round in the Discord server.
  • There are no draws allowed, intentional or otherwise. It is not possible to draw in game (ties are broken first by highest player health, then by most cards in deck, then the player who goes second wins)
  • Time Limit: Once a round is announced, players will have 45 minutes to complete their matches.
    • In the event of a round finishing before a match, the current game will be suspended. Both players should immediately stop play when time is called.
    • If a player leads in the match (has won more games than the other player) and a game is still ongoing, the player currently leading wins the match.
    • If the match is tied, a screenshot of the current gamestate will determine the winner, in the same manner as the game itself: The player with the highest life total will win, then the player with more cards left in their deck, then the player who went second in the game.
    • If the series is tied and players are in-between games, a third game will be immediately played with the same deck configuration used for the previous game, and after 10 turns (eg., the second player’s fifth turn) have passed, a screenshot of the game is taken and the winner is determined in the manner described above.
  • Late Players: If a player has not been contacted by their opponent within 5 minutes of a round starting or is not ready to play their game within 5 minutes of a round starting, contact the Tournament Organizer. The opponent will have 5 minutes from contacting the Tournament Organizer to be ready to play, and a game loss will be issued to the opponent. Players will proceed directly to game two, with sideboarding allowed prior to the game. If they do not show up at all, they will be given a match loss and be removed from the tournament
  • Disconnects: Disconnects do happen, but a stable connection is an important part of tournament play. If your opponent disconnects, please notify the Tournament Organizer. If they are able to return within 5 minutes, the game may continue as normal. Otherwise, the player who has disconnected will lose the current game and have 5 minutes from the end of the game to return and continue the match, or you will be assigned a match loss and dropped from the tournament.

Rules Violations

Being disqualified from a tournament invalidates all the Invitational Points you would have gained from that tournament, but does not prevent you from playing in future tournaments. Tournament bans are permanent but may be reviewed at a later date.

We rely on the honor system for many of the aspect of our tournament system, and ask that you respect that by behaving reasonably and respectfully. It is our goal to provide everyone with the best tournament experience possible and will do what we can to provide it.

Penalties for rule violations (as written below) are as follows. We reserve the right to increase the level of your punishment in accordance with the severity of your actions.

  • First offense: Warning from Tournament Organizer
  • Second offense: Match Loss
  • Third offense: Disqualified from the current tournament
  • Frequent or flagrant offenses: Ban from the Eternal Tournament Series

We reserve the right to give a match loss to, disqualify, or ban any player who we feel has intentionally attempted to exploit the system, even if they have not broken any rules currently listed here. We also reserve the right to make a final ruling that is different from ones listed below, if we feel that a different ruling will better fit the specific situation.

  • Deck Registration (Illegal Deck) – If a player registers a deck with an illegal deck or sideboard configuration (too many copies of a card, too many sideboard cards, etc) they will be contacted to alter it if the error is found before decklists become public. If the error is found after decklists become public, the error will be rectified in the simplest way possible:
    • Too many sideboard cards: The player will play the first fifteen legal sideboard cards they registered.
    • More than 4 copies of a card between main deck and side deck: The main deck copies are assumed to be correct. Copies beyond 4 will be removed.
    • Illegal Card: If a player registers a banned card or a card that doesn’t exist, that card will be removed from their decklist.
    • If any of these modifications render a player’s main deck ineligible for ranked play, the cards will be replaced with basic sigils. If the violation is serious enough, that player is disqualified from the tournament.
  • Unregistered Card– If you play or reveal a card in your deck that is not in your registered decklist (main or sideboard), you will receive a game loss. If you notice during the Mulligan phase / first turn, contact a TO, and take a screenshot of the card, a warning will be issued and the current game will be nullified and remade.
  • Sideboard Card in Mainboard Game – If you play or reveal a card in your deck that is not in your registered main deck but IS in your sideboard during the first game of a match, you will receive a game loss. However, you will be allowed to sideboard with your proper registered deck before playing additional games. If you notice during the Mulligan phase / first turn, contact a TO, and take a screenshot of the card, a warning will be issued and the current game will be nullified and remade.
  • Outside assistance – Discussing an ongoing match is not allowed. Getting assistance for building decks and testing is fine, but any outside assistance during a match is out.
  • Stream Sniping – Watching or otherwise receiving information from the streamed broadcast of a player you are currently playing is a violation of the rules. Watching streamers during tournament rounds you are not playing them is fine! However, once the round begins and you learn your opponent, you must immediately leave their stream until the match is over. Simply muting it is not good enough. While this is difficult to find and enforce, if a player provides plausible proof that you are Stream Sniping, you will receive a warning. This is considered a flagrant offence and you will be permanently banned for multiple offenses. Streamers are encouraged to stream on delay to discourage this tactic.
  • Immediate Concession – Any match that you play, you must actually play the match! You cannot snap concede a round without dropping from the tournament. If you do so, you will be dropped from the tournament.
  • Collusion/Prize Splitting/Match Fixing – While weekly tournaments have no cash prizes, the lure of an Invitational Qualification is strong. If it is suspected that one player intentionally threw a match to assist another player, the matter will be investigated.
  • Multiple Accounts – Registering for a single tournament using multiple accounts is not permitted. It is also prohibited to play in a tournament using multiple accounts regardless of whose account they are and who registered them. If it’s discovered that you are playing on multiple accounts, you will be disqualified from the tournament and the incident will be investigated to determine if an ETS ban is necessary.
  • False Identity – You may not play a tournament match on an account that you do not personally own, to ensure that all results are attributed to the correct player. Violaters will be disqualified and investigated.
  • Unsportsmanlike Conduct/Abuse – Sometimes you win and sometimes you lose. You are allowed (indeed encouraged) to congratulate your opponent on the win and maybe share some lighthearted salt about unlucky/lucky draws, but please do not harass your opponents or other players. If you have been asked to stop, you’ve crossed the line and need to stop complaining. Never call an opponent anything demeaning or inappropriate. They engaged you in a fair contest and you should respect that. If you feel that the contest was unfair (and I don’t mean unlucky) please consult the Tournament Organizer. This is considered a flagrant offense and you will be dropped and potentially banned after your first warning. Arguing with the TO after a final ruling has been called is considered Unsportsmanlike Conduct.
  • BM – BM is not in and of itself a rules violation. In moderation, such as torching your own face before making a lethal attack, it is harmless. However, excessive BM is exceedingly disrespectful towards your opponent and will not be tolerated. If frequent complaints about BM are made, your play will be investigated.
  • Slow Play – Yes, there are some difficult decisions to make, but you slow down the rest of the tournament. Complains of frequent slow play will result in an investigation. This also includes out-of-game slow play, such as taking an excessive amount of time to sideboard or accept/send challenges. Players who take more than 5 minutes to sideboard between games are considered to be playing slowly.
  • Infinite Loops – There are a few Infinite Loop cases that may occur in the ETS, due to the reduced restrictions (eg, no time limit, no free card limit) on friendly matches in Eternal.
    • An Infinite Loop that will eventually end the game, but will take a significant amount of time. For example, if you can infinitely reanimate and sacrifice an Umbren Reaper, but your opponent is at a very high amount of health, you may talk to a tournament organizer about spectating the game to verify that an infinite loop has been demonstrated to get a Game win.
    • An Infinite Loop that can be voluntarily ended by player choices. If you are in an Infinite Loop that does not advance the game state that can be broken by player choice, you must do so. Not doing so is considered Slow Play and may result in being given a game loss.
    • An Infinite Loop that cannot be voluntarily ended by player choices. If you are in an Infinite Loop that cannot be broken by any series of player choices and does not advance the game state, you will be given a game loss for that game.
  • Reasonable Limits – If we suspect you have broken any laws during the course of a tournament, we reserve the right to disqualify you and/or investigate.
  • False Report – If you constantly report the incorrect match results, you will be investigated and potentially disqualified and/or banned. In the event of a match dispute, a screenshot of your profiles recent match history should reveal the winner.
  • Tournament Organizer Discretion – These rules are not meant to be an exhaustive description of all occurrences that may occur during an event. Tournament Organizers may make rulings about occurrences as they see fit, as they come up. Tournament Organizer rulings are final.

Streaming Rules

For weekly events, participants are encouraged to stream their matches! We recommend that you use a stream delay of at least five minutes (preferably at least ten) and do not read your chat during matches in order to prohibit stream sniping and backseat coaching/outside assistance. However, for premiere level events participants will not be allowed to stream unless specifically asked to do so by the Tournament Organizer. Players are allowed to record their perspective for later video content (just not allowed to stream it live).

The official ETS stream has a 10 minute delay.
