Update 1.2.0
🕑 Added 2025-05-29 20:12:26 +0000 UTCSince the last update four months ago, we've been working on a wide range of features and improvements for CubeCobra. In the last update I talked about opening up avenues for new projects to benefit from CubeCobra with new integration points, and today I'm really excited to announce two new integrations, in addition to a couple new large features.
The first integration is with a new project, still in open beta, called Snapdrafter. Snapdrafter is currently only available as an android app and if you'd like to see it an iOS app, I'd encourage you to support the app here. Snapdrafter is an app that lets you take photos of your drafted deck, and save them to your phone as a text decklist file. From there, you can click the CubeCobra icon to import scanned decks into CubeCobra. I believe that creating an easy way to collect data for in-person drafts will make it feasible to do data analysis for in-person drafts of a cube. These imported decks won't just be a playtest draft object you're familiar with, we have added a new cube section called "Records" to track actual drafts of your cubes. This section is meant to be a data store, a place where data can be input or imported, in order to perform analysis on the performance of cards or strategies. It's still very basic, so if there is something you'd like to see in this section, please let us know.
The second integration is with a project you may have heard of before, Commander Spellbook. Commander Spellbook is the most comprehensive database for combos within magic. We've added a new analysis tab to cubes that allows you to see the combos that are available in your cube, with detailed information about each combo. If you feel a combo is missing, you can submit new combos here.
If you regularly follow development of the site, you may know that I retrain the ML system roughly once a year. I was unable to retrain this year due to our dataset outscaling the training infrastructure we had set up. This has been a pain point for users as newly printed cards that were outside of the training data were effectively invisible to the model at the time. We implemented some mitigation measures, so cards outside the training dataset are matched to similar cards. This has been an effective stopgap for now, and will help keep the system working well in between re-trainings. Fortunately we have recently had help from a contributor who refactored our training scripts, to be able to handle the scale of our dataset for many years going forward. I'm currently working on rebuilding this dataset and retraining the model, and I hope to have that done in the next month or two. There have been some new features that interact with the ML system, such as being able to view draftbot scores during playtest drafts, and also being able to view these scores in the pick-by-pick breakdown.
New Features
Added records tab, for tracking of practical draft data
Added combos analysis tab, using commander spellbook data
Added bot scores for pick-by-pick analysis and during playtest draft
Performance optimizations on draftbot calls, making playtest drafts smoother
Allow users to set default preferences in card searches
Added word count sort
Updated custom draft formats to fill restrictive slots before non-restrictive slots
Added mana breakdown for deck stats
Added filter for card notes
Added Mana Pool purchase links
Added purchase links for entire cubes and selected group of cards in a cube
Added user preferences for grid tightness
Add User auto blog preference, which determines whether "Create blog post" is checked or not by default (and defaults to false)
Async load cube or user followers when the modal is opened, page results for page load performance on popular cubes
Added spam mitigation measure warnings for improved UX
Allow custom back of card images to make the Transform button appear
Added power/toughness comparison filters
Support tag exact match searching
Added inner scrolling for large modals, have some buttons always visible
Return draft notifications to the solo, within CubeCobra bot drafts
Add notifications for Draftmancer draft imports
Performance improvements with fetching cube recommendations
Bug Fixes
Increased card tag color contrast to improve visibility
Fixed deck deletion
Fix duplicate card removals that also remove unintended cards
Fixed collector number sort
Allow card search with apostrophes
Card prices for 'Etched' finishes now show the correct price
Fixed failing drafts when basic lands are not lands (you know who you are)
Fix not using distinct card names for searches correctly
Fixed saving of new packages to correct format
Use short id if it exists in "Your Cubes" dropdown
Fix card name sorting on playtest data
Fix invalid dates in date added sorting
Fix vote package count being stored in the wrong attribute, not aligned with the vote count index.
Fix error where frontend causes a 404 on redirect because the short id changed.
Fix Playtest data CSV containing card ID instead of name, so different than the UI
Updated Tile component to use anchor instead of onClick so browser's normal ctrl/cmd click behavior opens the cube in a new tab.
Fix delete deck modal actions redirecting to the deck
Fix bug that resulted in Art Cards appearing before the actual cards
Prevent last step of a pack in custom draft format from being a "pass", which stalls the draft
Fixed trashing cards during playtest drafts
Fix matched cards in CSV upload not tracked when user is asked to correct misidentified cards
Fix blog post redirection on edit/delete if the cube is deleted
Fixed searching while not logged in
Fix color identity filter case sensitivity
Default card notes to empty string instead of null to fix filtering error
Fix drafts not finishing or ending in a weird state, related to pending picks and failing bot predictions
Technical Changes
Added spam mitigation measures
Split webpack into common and page-specific chunks, reducing page sizes
Started back-end typescript migration, migrated many files
Response time logging to help diagnose performance issues
Significantly increased unit test coverage
