Didn’t this site look different?

Yes, this is a new design. You can read all about the changes right here.

Hey! I’m noticing a bunch of duplicates of a particular (rare, uncommon, common…) Are you sure Draftsim isn’t broken? That’s not random!

Draftsim fills up your packs by picking a random card from each rarity and putting it in the appropriate slot in the pack. There is some checking within the pack to prevent duplicates or having zero cards of one color. But from pack-to-pack, there isn’t anything preventing the same card from being “opened” many times.

This is confusing, because the result is actually random. Even though your brain doesn’t believe it. If you flip a coin 100 times in a row, you are going to get clusters where you have 8-10 heads in a row, even though it’s “very unlikely.”

Real Magic packs are not random because they use a deterministic sequence to populate the packs – print runs. Not only might having real print runs in Draftsim raise the ire of WotC (because print runs are a trade secret), we also don’t have that data. It’s possible in the future that I will implement some kind of homegrown print run system for Draftsim, but it’s not in the cards for now….


Why does the autobuild (or draft suggestions) want me to put this tribal card in my deck? I don’t have any cards of that tribe.

At the moment, Draftsim doesn’t explicitly take synergy into account for its picks and deck building. This is a pretty complex problem, but I am working on it and hopefully we’ll see that in the future. If you want to learn more about the current drafting decision methodology, have a look here.


Why did this (expensive mythic rare) go fourth pick? That’s TOTALLY unrealistic!

Yes, although at your local store or FNM someone may take a bad card because it is worth $15, Draftsim is intended to simulate a competitive draft environment as closely as possible. The goal is for all of us to get better at drafting the best deck we can, isn’t it? A good draft simulator should give you a feel for what draft archetypes are possible in a set and should help you build card evaluation skills.

Card values change all the time and today’s chase mythic rare is often tomorrow’s $1 bulk card.

Plus you do realize these aren’t real cards right? They’re not worth anything 😉

For Masters sets I have implemented a “bots raredraft” button to better simulate drafts with an even higher number of expensive cards in them.


What in the world? Why is there a pack of (this set) as the last pack of my (different set) draft?

Depending on how long you’ve been around Magic, this is actually very typical. There have been many blocks (series of sets) where the later, smaller set makes up the first 2 packs of the draft and the earlier, bigger set is the final pack. If you’re unsure what the draft format should be, just do a quick Google search for the name of your set and “draft format”.


How do you get the ratings for the cards so dang fast? Don’t you need data to do this? Or professional reviews to base them on?

All the ratings are manually assigned by me (Dan). I play a lot of limited, including traveling to limited Grand Prix tournaments, so I have a good idea what’s up.

I scramble to rate all the cards ASAP as soon as Wizards reveals the full set, usually the Friday of the week before the prerelease. I want you to be able to be able to practice as soon as possible!

Later, I update the ratings every few weeks as the format evolves. You can see the ratings at any time by visiting the ratings page.


How do I export my sealed/draft decklist? I don’t see anything.

Once you finish building your deck, a list box will appear where you can copy/paste it into a .txt file. If you don’t want to actually build anything, just click the “autobuild” button and it will appear.


Draftsim is awesome! Is there any way I can show my support?

Thanks! If you want to give appreciation for the site, you can do so via Patreon. And if you can’t support Draftsim financially, you can always follow on Facebook and Twitter. And be sure to tell your friends about the site too!

Finally, if you are a software dev who loves Magic, I’m always looking for help with the site. Feel free to drop me a line at [email protected] and let me know what you’re interested in.
