Modern Horizons 3Historic and Brawl Pre-Bans

Historic

• Harbinger of the Seas
• Winter Moon
• Endurance
• Fury
• Grief
• Subtlety
• Solitude
• Flare of Fortitude
• Flare of Denial
• Flare of Malice
• Flare of Duplication
• Flare of Cultivation
• Enemy fetch lands

Modern Horizons 3introduces the largest change toHistoricto date when it comes to card power. We want to take as many cards as possible in the format while keeping true to our typical banning strategy. We have been cautious of cards that can be cast for free with alternative payments as we believe they are too fast for this format. So, it should not be surprising that we are banning the Evoke Elementals and Flare cycle forModern Horizons 3, but they will be playable inTimeless.

We believe the other two cards, Winter Moon and Harbinger of the Seas, are above the power level threshold for Historic. Both cards affect the opponent’s lands in a way we are cautious of in this format and will likely slow the game down.

Brawl

• Disruptor Flute

Finally, we want to prevent cards inBrawlthat can shut down a player’s commander completely, so Disruptor Flute is banned in Brawl.

MTG ArenaMatchmaking and You

A couple of weeks ago we shipped a bug onMTG Arenathat allowed players to reverse engineer some of the logic behind our matchmaking. While there is no security risk in this bug, it did create some conversation on the topic, so we wanted to take a minute to discuss what our goals are with matchmaking and what players can expect moving forward.

Our vision forMTG Arenais “Fast, funMagicfor everyone, anywhere.” Applying this to matchmaking in unranked modes, our goal is to let players build whatever decks that interest them and then provide as fair a match as possible. This means we’re looking to pair high-power decks against each other so those players can have the epic battles they’re looking for. Meanwhile, players who are building for fun, thematic matches are more likely to pair against others who are doing the same.

With a game as complex asMagic, however, no system will perfectly account for all the strategies, variables, and deck-building options available to players, let alone the myriad motivations those players have. In addition, we must make compromises between matchmaking precision and how long it takes players to find a match.

So, let’s discuss how we manage this (after a couple of caveats)…

First, the matchmaking we’re discussing today only applies to the Best-of-One play queues (and occasional pass events, like MidweekMagic, where you get to play for a timed duration instead of a set number of matches), and does not apply to Ranked play, Best-of-Three play, premier events, or events that have win/loss targets.

Second, we’re not going to share specific matchmaking details. While we know some players won’t like this choice, it helps us achieve our goal of fair matchmaking. When players have full transparency on how the system works, it is easier for certain players to exploit this information to create imbalanced match-ups. When this happens, predictably, more players adopt this strategy over time for fear of being disadvantaged, which means that not only are they creating even more imbalanced matches, they may not even be playing decks that they think are fun or interesting.

Now on to the discussion.

For Brawl (and Standard Brawl), the system looks at both your Commander and your deck, roughly evaluates the combined power level, with an emphasis on the Commander, and then tries to match you against decks of similar power level. If it is taking too long to find a good match, the system periodically increases the acceptable power level discrepancies until you are paired. As a rule of thumb, we’re hoping players are never waiting more than a minute or two for a match. For non-Brawl matches, the process is the same, but without the commander.

There are two key things to point out here. First, new cards will need play data before they are integrated into the power calculation, so they are the most likely to change between evaluations. Second, when making changes, we’re going to prioritize statistical outliers or the most popular cards for adjustment. Granularly managing thousands of cards is unlikely to be the best use of our team resources, so we’re going to focus on the most important areas first.

Beyond the relative power of the commander and the cards in a player’s deck, we incorporate player skill as part of our matchmaking in further service to finding fun and compelling matches for players. While it can be fun to win convincingly, we don’t want to regularly pit newer players who are learning the ropes against seasoned veterans with advanced skillsets and create situations where these outcomes are much more likely. Combining deck power and skill helps prevent that, while still allowing for these players to occasionally battle.

Moving forward, you can expect a few things. First, we’re going to fix the issue that gave players too much information. This will happen soon. Alongside that change, or shortly thereafter, we’ll make changes to our power ratings based on play patterns over the past few weeks. Again, our goal is for players to have fun, engaging matches that appropriately test their skill level.

Beyond this, we’ll continue to explore how we manage the power level portion of matchmaking in a sustainably responsive manner, where changes are regularly accounting for shifts in the metagame but don’t impact our ability to run other parts of the game. We’re not going to provide explicit timelines or windows in which this will happen, because doing so creates windows of opportunity for players to try and circumvent the system.

We’ve seen strong growth in Brawl over the last year, and we’re excited to find ways to better support Brawl players. While we know it is imperfect, using deck power matchmaking has been a cornerstone of supporting engaging games ofMagic, and we’ll continue explore ways to make it even better.

Card Styles Button Returns

Coming with theModern Horizons 3release is the return of the card styles button:

By toggling on the card styles button located in the upper-right corner of the deck builder, you will be able to see all the card styles available for your deck at once, and even card styles you don’t yet have in your collection!

This should make personalizing your decks to your style even easier!
