Recently I asked how many Commander decks people had. I got 8 responses, and along with my own numbers and my friend’s at CastFromExile, that’s 10. Not exactly a decent sample size, but it’ll have to do. I’d like to look at the numbers:
Me: 3 (just finished Glissa and played it for the first time Thursday!), though 4 if I won the lottery because I could justify another. So, well, 3.
aspookyskeleton: “I have two! And another one’s near completion.” So, 3.
mikerickson: “One: Rafiq of the Many. I’m looking to build one around Brion Stoutarm though.” I’ll count that as 2 then.
saangel: “I have a Teneb deck.” I’ll count that as 1.
confessionsofapuzzledwizard:”5+.” Not sure how much the + would be, so I’ll just count it as 5.
captainchemistry: “3 as of now but I have 2 in the works. And I might split one of them to make 2.” Let’s count that as 6.
Hazy Reverie: “Four right now. Two Commander decks—the wizards official ones—and two of my own. I went with Thraximundar and Sen Triplets for the other two.” 4 total.
Magic Junkie: “I generally have 4 playable decks. One control, one aggro, one fun deck and one to make people hate their lives. I also have a fifth in the works for an experiment.” 5.
WizardsvsRobots: “I may or may not have 9. But they oftentimes find themselves falling apart after repeated failure, usually only to be replaced by new ones.” I’ll consider this response under the “may” option, which makes it at 9.
Here’s what we have then:
3, 4, 3, 2, 1, 5, 6, 4, 5, and 9 decks, or, in ascending order:
1, 2, 3, 3, 4, 4, 5, 5, 6, and 9.
In our tiny little sample, then, it seems that the average number of decks is slightly higher than 4 (4.2, to be exact), with the median number of decks at 4.
Outside of this sample, I know of several individuals from listening to podcasts and the guy at my local shop that has 1 monoGreen, 1 5-color, and 1 deck for each 2- and 3-color combination that there are people out there with 20+ decks. This would certainly affect the average, perhaps overly so. In statistics, then, the median would likely be used instead of the average. Plenty of 1s and 2s would balance out the median near where it is for this sample better than they would balance out the average when several 20+s values are entered. Thus I wouldn’t expect the median value to stray to far from the lower numbers like what was found here, and the median would likely be a better measure of central tendency than the average with such a data set.
Or, in laymen’s terms, 4 seems to be pretty reasonable among the 10 of us. If you have around 4 and were worrying you had too many, don’t fret, and if you have 3 and were wondering about a 4th, as long as you have the money, go for it! If you have 20, though, maybe we should have a talk. Seriously, how do you have time for so many?! (Really, I’d like to know. And if you don’t have time for all of them, maybe you really should consider selling them. Anyone try selling an entire deck list instead of singles?)
