32:T66a,md`# Exploring Magic the Gathering card performance in Limited This is an exploratory analysis for [Magic the Gathering](https://magic.wizards.com/) (MTG) individual card performance from the latest set: [Adventures in the Forgotten Realms](https://magic.wizards.com/en/articles/archive/card-image-gallery/adventures-in-the-forgotten-realms) (AFR), more specifically in the limited format. The source data is from [17 lands public datasets](https://www.17lands.com/public_datasets) and it was tweaked around in this [colab notebook](https://colab.research.google.com/drive/12NPk9FcjNGu5MG-TkhnACnPTaFOggx0n?usp=sharing) to become more fit for this visualization exercise (final result of the data tweaking is in this [gist](https://gist.github.com/ltostes/9ad08a063a26cc9948082939a9161ec3)). The approach used in this analysis was greatly inspired by the article [Using WR (Win Rate) Data](https://www.17lands.com/blog/using_wr_data) by [Sierkovitz](https://twitter.com/Sierkovitz?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor). Feel free to jump straight to the [Data Playground](https://observablehq.com/@ltostes/exploring-mtg-card-performance-in-limited#data_playground_bullet) session to play around with the data yourself if you'd like! > _Disclaimer: This analysis is meant to serve as a good friend and not as an absolute truth._ In the meantime if you have any ideias you would like to suggest or share: drop me a line in my twitter [@eltostes](https://twitter.com/eltostes). *Many thanks to [@diogueraT](https://twitter.com/diogueraT) who helped a lot with his insightful MTG mind and skills.* Now let's get to it! `33:Tac0,md` One of the major concepts we use when discussing MTG data is Win Rate (or WR, as a short hand). This number represents the percentage of games that were won when compared to the total number of games played. So when we are talking about a specific card's Win Rate, we mean the win rate of games in which this card was either in the deck or played. #### WR serves as a good performance indicator, but... In my view WR is one of the best indicators we have for performance. But when we are looking specifically towards a card's performance, this number might be affected by other factors rather than the pure value of the card itself. For instance, if the card's color is inherently stronger, it might mean that this card has a better chance of winning not because of its own power but because of the other cards that most often come with it in a deck. #### Lift Here we will borrow a concept often used when we talk about [causality](https://matheusfacure.github.io/python-causality-handbook/01-Introduction-To-Causality.html) and AB testing: *Lift*. In an oversimplified explanation, lift is the observed effect when we introduce our interest actor in an environment versus one environment where we don't introduce it. In practical terms our aim here is to have the environment *with* the actor to be as equivalent as possible to the environment *without* the actor we are comparing to. (You will find most commonly the wording *treatment* in replacement of the _actor_ we used here.) #### WR Lift In our case here, to calculate the Lift in terms of WR we want to isolate the performance difference of when we introduce the card in a game vs when it wasn't introduced. The most ideal situation would be to have a match-to-match comparison with the *exact same scenario* (meaning same deck and same opponent - deck and person) with the sole difference of having (vs not having) the card in your deck. Since we are not dealing with experiment-specific data that is not something we are able to have. One option we do have with his data is comparing the difference in WR when the card was made available in the game (you either drew it in the opening hand or later throughout the game) vs when it was in the deck but you didn't actually get a chance to play it (because it just wasn't drawn). The fact that we use the same deck containing the card as a baseline helps us get closer to a cleaner comparison, since the decks that fit this card are more likely to be similar among each other than decks that don't contain this card. With all this in mind, we will base this analysis in this perspective: > **Card WR Lift (Δ%)** = ***playable WR %*** *(when card was drawn)* - ***not playable WR %*** *(when card was in deck but wasn't drawn)* `34:T729,{ const example_data = [ { card: 'Example card name', wr_1: .52, wr_2: .61, plays: 1000, wins: 600 } ]; const tooltip = d => "Details\nYes, we will have details in the tooltip too! Including the card image :)"; const bottom_text = 'In this example, the WinRate lift is positive: +9%, which means the card improved the win rate when available'; const graph = Plot.plot({ marginLeft: 150, height: 120, grid: true, y: { label: null }, x: { label: 'Win rate %', tickFormat: '%', axis: 'top', domain: [.4, .75] }, color: { domain: [1], range: ["#00733e"] }, marks: [ , Plot.dot(example_data, { x: 'wr_1', r: 1, y: 'card', title: tooltip }), Plot.dot(example_data, { x: 'wr_2', r: 3, y: 'card', title: tooltip }), Plot.ruleY(example_data, { x1: 'wr_1', x2: 'wr_2', y: 'card', strokeOpacity: 0.3, title: tooltip }), Plot.text(example_data, { x: 'wr_1', y: 'card', dy: -7, text: d => `WR when in deck` }), Plot.text(example_data, { x: 'wr_1', y: 'card', dy: 14, text: d => `but not drawn` }), Plot.text(example_data, { x: 'wr_2', y: 'card', dy: -12, text: d => 'WR when drawn' }), Plot.text(example_data, { x: 'wr_2', y: 'card', fill: 'olivedrab', textAnchor: 'start', text: d => '+9%', dx: 7, fontWeight: 'bold' }), Plot.text(example_data, { x: 'wr_2', y: 'card', textAnchor: 'start', text: d => '-> and this is the WR Lift', dx: 35 }) ], caption: 'Explanation' }); return addTooltips(graph, {}); }35:T5f1,md` As usual, we see the **#1** most played for both colors being the strong call for any MTG Limited draft: *Removal*. The numbers seem to agree:**+3.9% WR Lift** when available for [Dragon's Fire](https://scryfall.com/card/afr/139/dragons-fire) and an amazing **+5.8%** for [Grim Bounty](https://scryfall.com/card/afr/106/grim-bounty). Relieving to see they're doing well in this perspective too, means their speed and power is likely compatible with the format. More to the bottom of the most played rank, we see two over-performers in both colors: - [Vampire Spawn](https://scryfall.com/card/afr/123/vampire-spawn) delivering a solid WR when made available at **60%** (just behind the black's favourite removal: [Grim Bounty](https://scryfall.com/card/afr/106/grim-bounty)) - [Price of Loyalty](https://scryfall.com/card/afr/159/price-of-loyalty) with an astounding WR Lift of **+4.4%** for red's #10 , boosting its *playable* WR to even higher than the solid [Dragon's Fire](https://scryfall.com/card/afr/139/dragons-fire) removal at **61%**. On the bad news side, we see red's #9 [Armory Veteran](https://scryfall.com/card/afr/130/armory-veteran) pushing the WR down **-2.5%** when available, a strong sign of over-ratedness. One thing that does come to mind is that it is not greatly synergetic with the so-called strongest archetype (in BR), as it fits better the WR equips archetype - which has considerably lower WR in general. Perhaps this number means we shouldn't use it as much in the BR archetype. `36:T88b,md` The first thing we can note is that although the ${mtg_symbols.get( 'white' )} **White** cards are more played than ${mtg_symbols.get( 'green' )} **Green** cards, they don't have the highest total card WR among the 2 (the vertical stripe illustrates the group's total card WR). *I won't mention ${mtg_symbols.get( 'blue' )} Blue's total card WR because it's not all that exciting*. Looking at each color's **WR Lift**, I get the feeling that the 17 Lands Arena players already kind of figured out the ${mtg_symbols.get( 'green' )} **Green** commons. The top most played 10 seem to be quite well performing and in a neat *WR & WR Lift* order. The only one that we could reflect a bit more about is #10 [Sylvan Shepherd](https://scryfall.com/card/afr/206/sylvan-shepherd) which is the only card with playable WR to the left of the color's average WR. Its WR Lift also shows it doesn't contribute a whole lot to its deck's gameplay. *Perhaps the attacking condition is not so favourable in its synergetic WG archetype?* White and Blue on the other hand have interesting behaviours. Their most played removals (${mtg_symbols.get( 'white' )} [Minimus Containment](https://scryfall.com/card/afr/24/minimus-containment) and ${mtg_symbols.get( 'blue' )} [Charmed Sleep](https://scryfall.com/card/afr/50/charmed-sleep)) don't seem to affect the gameplay as much as the other color's removals. My take would be the fact that they are enchantments so the flexible cards that allow to destroy an enchantment as an extra option (such as [Dawnbringer Cleric](https://scryfall.com/card/afr/9/dawnbringer-cleric), white's #9 in this list) might facilitate card disadvantage. It is interesting to see that both these colors have clear over-performers: ${mtg_symbols.get( 'blue' )}[Air-cult Elemental](https://scryfall.com/card/afr/45/air-cult-elemental) and ${mtg_symbols.get( 'white' )}[Veteran Dungeoneer](https://scryfall.com/card/afr/40/veteran-dungeoneer). They both deliver around **+5% WR Lift** which is an impressive figure given their position on the list. *I confess I haven't played all that much with them yet, so maybe you have some ideas of why that would be so?* `37:T42c,md`## #2: The Overrated and Underrated niches I recently came across an amazing [article](https://mtgazone.com/the-most-overrated-and-underrated-cards-in-forgotten-realms-draft/) (*by MTG Pro Player [Chris Kvartek](https://mtgazone.com/author/chris-kvartek/)*) in which he highlighted some *Overrated* and *Underrated* cards and themes in this set. I personally enjoy reading approaches using the well-known *Quadrant Theory*, (greatly revisited in [this article](https://strategy.channelfireball.com/all-strategy/mtg/quadrant-theory-revisited/) by [Pawel Sierocinski](https://strategy.channelfireball.com/all-strategy/category/mtg/channelmagic-articles/pawel-sierocinski/)). I was also amazed by the timing of its release since it was at the very same moment I was playing around with the data available in this notebook. After reading it I figured this is an amazing opportunity to use his findings to review the visualization method we're proposing here. So let's have a look at two different themes he pointed out in the article: **Equipment** and **Lands**. `38:T4b1,md` It doesn't take much to visualize that most of the equipment in this set is indeed **under-performing** (and quite a bit I'd say). The playable WR is in general below the total card's colors WR and most of them have a **negative WR Lift** causing the WR to drop much more often than to increase. The special mentions in the article do point out correctly that ${mtg_symbols.get( 'white' )}[Plate Armor](https://scryfall.com/card/afr/32/plate-armor) is a keeper (**+2.3% WR Lift**), but the data doesn't agree as much that ${mtg_symbols.get( 'red' )}[Goblin Morningstar](https://scryfall.com/card/afr/145/goblin-morningstar) can be considered a premium contributor. Although it is the best in its color and doesn't have a WR Lift as negative as the other ones: **-0.2%**. The ones that we see most difference than what was pointed out are the [+2 Mace](https://scryfall.com/card/afr/1/+2-mace) that under-delivers a lot at **-5.4% WR Lift**, and ${mtg_symbols.get( 'black' )} Black's premium [Reaper's Talisman](https://scryfall.com/card/afr/117/reapers-talisman) that shakes the game positively, incrementing WR at **+2.4%** reaching the highest WR when playable amongst all equipments. `39:T573,md` The creature lands, on the other hand, are clear **over-performers**. As you can see in the graph, all of them deliver a **positive WR Lift**. Great highlight to ${mtg_symbols.get( 'blue' )}[Hall of Storm Giants](https://scryfall.com/card/afr/257/hall-of-storm-giants) that punches its decks win rate in **+6.4%** and both ${mtg_symbols.get( 'red' )}[Den of the Bugbear](https://scryfall.com/card/afr/254/den-of-the-bugbear) & ${mtg_symbols.get( 'black' )}[Hive of the Eye Tyrant](https://scryfall.com/card/afr/258/hive-of-the-eye-tyrant) that even in a high WR environment (BR) manage to boost the WR when available by around **+3%**. ${mtg_symbols.get( 'green' )} [Lair of the Hydra](https://scryfall.com/card/afr/259/lair-of-the-hydra) doesn't fall behind, contributing with **+3.8%**. The least performing of them is ${mtg_symbols.get( 'white' )}[Cave of the Frost Dragon](https://scryfall.com/card/afr/253/cave-of-the-frost-dragon) but it still contributes to WR in **+1.6%** when available. As a base comparison for better picking, below there is a graph that includes rare cards from each color that have similar play amounts with its respective creature land. Of course there are similar rares that beat the creature lands in terms of WR and WR Lift, but I hand-picked these below as an example of picks where the data suggests they aren't as good as the creature lands. `3a:T5eb,{ if (selected_rarities.length == 0) { return html`

MTG is one of the few games I play at an irresponsible level, and it was a breeze to work on finding ways to visualize and gather insight using its data. I'm happy to say this is also a tool suitable for recurrence, so you can wait the very same analysis available for any future sets (or datasets). My next step is to turn this post into a series of MTG and/or Gaming data viz articles. I do have some candidates in mind: 1. MTG Performance for combinations of cards instead of single cards, using genetic algorithms to find the most interesting combinations. 2. Overview of WR and disputes between combinations of colors (BG vs WUB, and so on). 3. Deep dive into in-game data for situational-insight: should you try to speed up a game, or try to make the most value out of each card in a given scenario? (Quadrant Theory based) And of course, I'd be glad to hear feedback and ideas for new topics!
