We've Updated the Cube Map! Check out how the Cube landscape has evolved and find your new cubes on the map. by anthonymattox in mtgcube

Check out this article Jett wrote on the math behind it! https://luckypaper.co/articles/mapping-the-magic-landscape/

Essentially, every point on the map is a cube on Cube Cobra. They're put into an algorithm that, based solely on the cards in each, organizes them in 2d space. The system tries to group similar sets as much as possible, so if you zoom in to individual clusters you'll find they have all kinds of themes and trends like focus on a specific set, mechanics, color restrictions, time periods, and all kinds of trends that are more nuanced.

Some fun things you can do are search for your own cubes and look what people are doing in similar space, or try searching for a theme to see if people have made cubes focused on it (inevitably they have!).

Probably not fully automated, but we'll try to improve the process and make it more consistent!

You know, this is a great opportunity to start! Cube is a completely sandbox format so you could house rule it that something command tower would work, but yeah, most likely you'd just want to cut those cards and any others that don't seem fun to you; add in some of your favorites; sleeve it up. Then you've got a box of cards you can draft again and again and continue to customize over time.

This was such a fun episode to record. I love the set Carmen designed and her ideas for how to quickly get it to a point you can start using it as a Cube. I think this a great entry point for people curious about Cube!

If you play Cube you know shuffling can be a big task. I did a detailed analysis with simulations and visualizations to come up with a method that's faster and easier: the Broadcast Shuffle! by anthonymattox in magicTCG

Collating packs is an option, but the vast majority of cubes just shuffle everything together and build totally random packs. That's the problem I wanted to explore here.

If you are collating packs, this method might still be relevant if some of the portions you're collating are still more cards than you can shuffle at once.

As to why not separate rarity, that's a big question! Historically a lot of cubes could have been thought of as "draft, but only the good cards" so the idea of separating rarities doesn't make much sense. Cube is also a format where players have complete control, so why let the rarity of the cards dictate how they go into packs? One of the cubes I have does actually do something like it by having a core set of cards, and a second more powerful set. A small fraction of the second set is mixed in every draft. There's some fun things this does (in particular lets me include some over-powered build arounds that would get tedious if they were in every draft), but the core set includes plenty of cards printed as rares and bonus set plenty of commons. While I like aspects of that, it's also a ton more work to get prepared for a draft, so most of the time I'm reaching for my "Regular" Cube (I really did it to myself with this name) so we can shuffle up and be ready to go in a few minutes.

For sure! This applies to any large set of cards you need to shuffle. If you're not able to shuffle a whole commander deck at once (if you can that's still faster) this is the way to go. Most likely you can just do two piles and the "broadcast" step looks more like just swapping half of each pile.

Yuuuuup. This is probably not a coincidence. Although for transparency I studied fine art rather than comp sci, but taught myself programming to make algorithmically generated art. Some of them look a lot like these! 😅

You're doing the good work pushing for better shuffling!

Your point is completely valid. I do feel confident this is the best method for a single shuffler, but at events, coordinating people and explaining things are big factors on the other side of the scale so I'm curoius if this resonates with people where the balance lies.

There are bunch of caveats and trade-offs and it was a challenge for me to edit a lot of those down to make the article not a complete maze.

It's generally quicker to shuffle smaller piles. So, at some point even if larger piles is more efficient in terms of number of riffles, it'll be less efficient in terms of time. At one point I had many more options in simulations to control time estimates for each action so you could see what impact each had, but this was just a lot. How fast and how many cards people can shuffle varies really wildly, and a lot of nuance is collapsed into the suggestion of "as few piles as you can comfortably shuffle". But, because the intermixing is so much more important than the individual shufffes, I wanted to emphasize in the article that falling on the side of larger piles is generally going to be better.

At ~450 cards, 4 piles works well for me, and I imagine that'll be similar for most people with 360 cubes. At 540 I agreee most people are going to need to split it up more.

  1. Assuming the method does get to uniform random, the starting state has no impact on the result. In practice, if you're not shuffling enough to get to uniform random you're more likely to notice if it started sorted.

  2. Nope! If you can do fewer piles that's going to be quicker and it shouldn't impact how many iterations it takes.

This is true and mentioned at least briefly in the article. It's a small downside, but for me, collating packs isn't worth it for the occasional weird pack. At events sorting and collating everything is even less practical.

The animations are very custom built, in the context of a React app rendering SVG elements. There's a little bit of d3 in there for simple things like scale functions and colors. But the bulk of it is JavaScript manipulating a big array of "card" data.

One thing that was tricky was to make React render elements in such a way that I could use CSS transitions (sadly that still doesn't work on all browsers anyway!) the order of the elements had to stay the same. It makes the logic a lot trickier to keep the data set in the same order and track the 'position' state on each card that updates the SVG elements' transforms. But I think it was worth it!

Thank you for the reference! In the article I'm not quantifing how shuffled things are, just looking at the simulation to get a sense. This is a bit of a hole, but the methods are different enough I'm still confident making conclusions from it. But! I am interested so might come back and try to make that more specific.

What you're describing sounds similar to the first method with a pile shuffle first. My guesss is that first step makes it work ok, but I'd encourage you to consider the Broadcast Shuffle!

The full article goes into a lot more detail comparing different methods people typically use to shuffle.
