Why not draft a random cube on Cube Tutor? Eligible cubes are active and have at least 360 cards.

devblog  New Release: Nut Collector 1.0

Time for a new release and one named after my first ever favourite card, Nut Collector!

Before I get into the specifics of this release I'd like to talk a bit about the Champion Program and my commitments to the community. As many of you will know I recently surpassed my Part Time Goal on Patreon ( – THANK YOU again!) so this means that I am officially working 1-2 days a week on Cube Tutor building new features and improving existing ones. Part of this commitment is to ship two releases of new features and bug fixes each and every month which essentially means a release every two weeks or after every 2-4 working days. For each release I like to focus on 1-2 decent sized Feature Requests ( whilst also finding time for small bug reports/other suggestions from the community. What I've found so far is that 2-4 days just isn't enough time to build, test and deliver some of the larger items requested through the new voting system. Indeed some of the most requested items ('Simulated Drafts', 'See picks after saving deck') are large enough to perhaps take longer than a months worth of part time effort.

What all of this means is that I'd like to build some flexibility into my commitment to accommodate some of these larger features. This means that each month on my Part Time Tier I will deliver either:

A) Two Medium Releases, one every two weeks.

B) One Large Release, once a month.

C) An update on an Extra Large release. For cases where I simply cannot complete a large feature in a month (for example: A new UI for Mobile!).

All of these releases will be accompanied by their 'bugfix' releases, e.g. Nut Collector 1.1, Nut Collector 1.2 etc.

Please let me know what you think of this proposal, and feel free to send me a [SPOILER ALERT] message through the new Conversations system [/SPOILER ALERT] with your thoughts.

On to the release, and this one's a doozy. Under the new classification system it would certainly be considered a Large.

Cube Tutor is essentially a social network but you wouldn't really know that at the moment. Many users have complained that they don't feel connected to the people who are interacting with their content. One user even went as far as to say that leaving a comment on a deck felt like “throwing it into a black hole”. This release has been all about improving the community aspect of Cube Tutor to make it easier for you guys to communicate with each other and collaborate on building your cubes.

New Features

  • Cube Tutor Conversations – You can now send personal messages to any other user on Cube Tutor! The interface should be fairly familiar to anyone with a smart phone in 2015 and acts more like a chat window than an email messaging system. The profile bar has a new Envelope icon that will notify you of any new messages. You can send a message to a user by either:

  • Email Alerts – Whenever someone interacts with some of your content, or whenever one of your followed cubes is updated you will receive an email notification. Please ensure that your email address is correctly set up here: You can configure which email notifications that you want to receive here: In this first release, emails will be sent out when:

    • Someone comments on your deck, cube update, forum thread, feature request or Castle AI pick report.

    • Someone comments on a deck built from your cube.

    • Someone builds a deck from your cube.

    • Someone replies to a comment that you've made.

    • A cube that you follow is updated (if that update has a title).

  • Primary Cube Id – If you have multiple cubes, you can now specify through My Account which of those cubes is your Primary cube. This will be the default cube that you are redirected to after login. It is also the cube that people will be able to draft when they click on your username.

Bug Fixes/Minor Fixes/Other

  • The deck page now has a link to the user who drafted the deck.

  • The cube menu now has a link to the user who owns the cube.
  • Fixed an annoying scroll in Chrome when editing your cube.

  • The card image window now appears in a visible position when you hover over a card name at the bottom or right of the screen.

  • Filtering by sub type on the Top Cards page now works properly.

  • The My Account pages no longer revert the active cube back to “Ben's cube”.

  • Fixed a bug where new members were not able to post a new topic on their forum.

  • Fixed a bug where forum topic replies could end up on the wrong topic when using multiple tabs.

  • You should now be able to click on a username everywhere on the site. Let me know if you find somewhere where you cannot.

  • Implemented a new process for gathering card information and images for new sets and those which do no appear on

  • Fixed a bug where changing a card's set to Beta (B) would sometimes set it to Beatdown (BD) instead.

  • The 'Reset Cube' and 'Delete Cube' operations have been sped up significantly.

  • New Featured Cube: Medieval Cube!

Castle AI

The tags on over 1000 additional cards have now been approved meaning that Castle AI should now perform better on Pauper and Peasant cubes. In addition I've reviewed every report so far and provided my own feedback.

New Sets

Using the new system for gathering card information I have added the following sets to Cube Tutor:

  • From the Vault: Angels

  • Ugin's Fate Promos

  • Duel Deck: Zendikar vs Eldrazi

  • Magic Online: Tempest Remastered

Note that we are still (sadly) missing the following as they don't appear on OR our new source.

  • Origins Clash Pack

  • SDCC 2015 cards

  • Game Day Languish

  • Origins & M15 Intro Pack Promos.

Resolved Feature Requests after this release

  • Feature 80 - Set the own cube as landing page after log in

  • Feature 95 - Link to Name of Drafter

  • Feature 104 - User Pms

  • Feature 114 - Card Image Window - Show up where visible

  • Feature 134 - Email Notifications when Cubes you Follow have a Blog Post

The Future

This is just the start of my improvements to the social aspect of Cube Tutor. I will be adding emails for more 'events' in the near future as well as moving towards a global Cube Tutor Forum.

I hope that you like this release, and as ever please get in touch with me through the usual channels if you have any suggestions or requests.

Happy Cubing!

devblog  New Release: Meditate 1.1

People often ask me this question:

I've just created a cube on Cube Tutor. Why are the draft bots passing me Black Lotus?”

The simple answer is because you haven't trained them yet! The basic AI (Cube Tutor AI) makes its decisions based on your observed pick orders (the Draft Charts on your Analysis page), and without any data they pick semi-randomly to start with.

Whilst this makes sense it isn't very clear, which is why I've decided to introduce a new concept; the AI Rating. This is a numerical representation of how trained your bots are, the minimum being 1 and the maximum 100. If you've done enough drafts for the AI to have a good idea of how to rate every card in your list then you will have the maximum score.

Not only should this make things clearer for new members but it will also help established members to work out whether they've seeded their draft bots with enough data after an update.

New Features

  • AI Rating – A numerical representation of how trained your Cube Tutor AI bots are. This appears on the Draft page and under the summary section of your cube blog.

Bug Fixes

  • Sorting by tags on the Edit List page no longer causes an error.

  • Fixed an issue where it wasn't possible to close images such as the Cube Image once they'd been clicked on.

  • Fixed some styling issues on the Draft & Analysis pages.

devblog  New Release: Meditate 1.0

It's been a while since I named a release after a Magic card and I want to get back into the habit of doing this again. This is the first official release on my Part Time milestone ( and I couldn't be happier that you guys helped me to get here!

As promised I have focussed on steering the ship in the direction that the Champion community have requested through the Feature Voting system (Feature Votes). This time around I've focussed mostly on some improvements to the Edit List page so without further adieu I present the content of Meditate 1.0:

  • Feature Request 14 – Mass Edit Functionality. I've had a few requests to implement a faster way to edit sections of your list in bulk. For example, “I'd like to set all of my Origins additions to foil in one go”. Well now you can! I've added a 'Mass Edit' section to the Edit List page where you can:

    • Select a group of cards either by filtering them or selecting them individually.

    • Set a change to any of the following: Colour Profile, CMC, Rarity, Super Type, Pimp or Tags.

    • Save that change for all of the cards in the selected group.

    Note that Mass Edits cannot be undone so please ensure that you have defined them correctly before hitting 'Save'.

  • Feature Request 69 – 'Suggest Replacements' Improvements. This one small section of the site produces probably the most confusion! It is the first thing that I ever built for Cube Tutor and as such it's been long overdue an update. I've completely overhauled the way that you add, remove and replace cards in your cube. For people who are wondering how to get the little blue 'replace' icon to appear in your blog posts hopefully this should make it clearer.

    • To Add a card – Just type it in to the 'Add Card' box, select it and hit 'Just Add'.

    • To Remove a card – Type it in to the new 'Remove Card' box and hit 'Remove/Replace'. Note that you can still remove cards through the main grid.

    • To Replace a card – Type a card into both the 'Add Card' and 'Remove Card' boxes and hit Remove/Replace.

    • Suggest Replacements has been renamed to Suggest Removals to make the intent of this function clearer. To use it type a card into 'Add Card' and press 'Suggest Removals'.

    • You will see a list of cards that are already in your list that are similar to the new card that you could remove. Hitting 'Remove' will save the update to your Change Set. The popup dialog has been removed to improve performance.

    • The algorithm that ranks these cards has been improved to weight cards of the same colour profile a lot higher.

  • Feature Request 40Improvements to Deck Commenting. Your 'Decks' page now shows the number of comments for each deck to make it clearer which decks are being discussed. In addition deck comments now properly display line breaks when these are used.

  • Feature Request 30 – Increase the maximum Pack Size when drafting. This has been increased from 22 to 30 cards.

  • The styling of the Filter and other functions on the Edit List page have been unified.

  • Average Cubes have been updated.

I hope that you guys like the improvements in this release. If you want to help to shape the future of the site and get some cool new toys for your account then please consider becoming a Cube Tutor Champion:

As ever please keep your feedback coming in through Facebook, Twitter and Email.

devblog  New Release: 'Top Cards' page

I was thinking about holding this feature back for a larger release but it has been requested SO MANY times and was also voted for by the Champion community recently ( so I decided it would just be best to release it straight away. You can now see the 'Top Cards' on Cube Tutor here: Sorting the grid by Cube Count will show you the most popular cards based on how many cubes that they appear in (please ignore 'Ow' which only features so frequently because it is often picked up from mis-spellings through the Bulk Uploader). You can also sort the grid by Pick Percentage which gives you the Global Pick Order (i.e. highest picked cards in Draft) that is used by Castle AI bots. We also have a new Featured Cube – KingNeb's Altered Art cube which really showcases what you can do with the new 'Upload Card Scans' feature of a Cube Tutor Champion account. If you enjoy using Cube Tutor and would like to get a bit more out of your account, or just want to support the site then please do consider becoming a Champion: I'm tantalizingly close to my Part Time Milestone now! Happy Cubing! - Ben

devblog  Added: Origins, Champion Features, Removed: Spammers (hopefully!)

We've been having a big problem with spammers the last couple of days. I've put in a few measures to reduce their impact on the site, and also to help me detect and prevent them from using it in the future... In order to get these changes out I'm also putting live a few features that I've been working on over the last few days. I haven't had as much time to test these as I'd like so please let me know if you come across any problems! We also have Origins! I'm sorry that it's taken so long for this update, and i'll look to speed things up for the next set release.. please bear with me! Here is the complete list of changes:

  • Added Origins
  • Users may now only post one forum thread per day. This is hopefully an interim solution until I find a better way to deal with these spammers.
  • Champion Feature Request 6 – Working 'Remember Me' function. The 'Remember Me' box on the login page should now work properly and you should no longer have to log in multiple times per day. It should also work across multiple devices. There was a lot of work involved in this change, so do let me know if you find a bug.
  • Champion Feature Request 55 – Collector's Edition Prices. TCGPlayer list these in a rather bizarre, non-standard way. I finally found out how to get hold of these prices through the API so you can now see them on your price page.
  • Marking individual cards as Owned or Not Owned on the Price page no longer causes the page to scroll back to the top.
  • When filtering the View Curve page, the number of cards in the resulting set is now properly updated.
  • It is no longer possible to attempt to load the prices for an empty cube, which would previously load indefinitely.
  • Added a few new user-requested pimp types: Stamped, Crimped, Full Art, Artist Altered.
