Why Are We Making These Changes?

We've been working on improvements to the Omnidex decklist submission process to reduce the likelihood of players accidentally submitting illegal decklists. While our previous system prioritized flexibility across different formats, we've decided to place a greater emphasis on making the experience easier and more reliable for players participating in current competitive events.

Alongside these improvements, we're also introducing Revealed Champions, a feature intended to create a more level playing field at competitive events. We want to ensure that players have access to the same basic information about their opponents, regardless of whether they have a large network of players to share information with.

Decklist Validation

What It Means

Mechanically, this will help prevent decklist issues by having Omnidex automatically catch most forms of illegal decklists.

What Issue Does This Fix?

In the past, Omnidex has allowed players to submit a decklist with no validation whatsoever. For example, this meant that players could submit a decklist with 10 of the same card, 20 material deck cards, or 10 main deck cards. Omnidex would never stop an illegal decklist from being submitted, often leading to penalties for players who didn’t recognize their mistakes.

While this update doesn’t completely close all of the issues (as many of these submissions could still be legal for a Pantheon deck or a special format), and the responsibility still lies solely with the player submitting the decklist to ensure that it is both correct and legal, it should help more mistakes be caught before they lead to penalties in the future.

Revealed Champions

What It Means

With this update, we are also adding the feature where, during events where decklists are submitted, each player's champions will be visible on Omnidex at the beginning of round one.

What Issue Does This Fix?

This change is intended to level the playing field at larger competitive events, particularly for individuals who may not have a team or a large network of people to talk to about matchups. By making each player's champion publicly available, we hope to reduce the advantages that come from having access to information that other players may not have.

From a competitive standpoint, you can gain a massive advantage by knowing what your opponent is playing before you sit down. You might make different actions on your first turn. You might Glimpse differently. You might take different lines. By having a large network of friends or players who may have played against your last opponent, or maybe watched them play, you can get a step up before you even shuffle your deck.

While we recognize that scouting and gathering information are part of competitive play, we want to ensure that every player has access to the same basic information about their opponent, regardless of their connections within the community.

Why Not Open Decklists?

A different solution to this advantage would be to have always open decklists. We didn’t choose to go down that route because we felt that it would impact deckbuilding too much, and we still wanted players to build decks that had some amount of mystery. We felt our current solution was one that still allowed for more creative deckbuilding, while also removing a lot of the aforementioned advantages that can be gained from not having this feature available.


These changes will be live for the upcoming Ascent Osaka. We’re excited to see these updates in action, and we look forward to continuing to improve in the future!
