Deterministic Commander analysis for deckbuilding and playgroups
bluecore.cards is a platform for analysing and building Magic: The Gathering Commander decks. It combines an explainable bracket result with practical suggestions, saved decks, and features designed around recurring playgroups.
The challenge
Commander decks cannot be usefully explained by an arbitrary single score: card identity, official bracket rules, and interactions all need to be considered together. The analysis also had to be transparent enough to give players a shared basis for pre-game conversations.
The solution
Decklists are resolved through Scryfall and then evaluated by a deterministic bracket engine. The interface explains the outcome, groups suggestions into shareable categories, and extends the analyser with a builder, saved decks, precons, friends, playgroups, and meta features.
The outcome
The result is a live bilingual Commander platform that brings analysis, deck management, community features, and editorial content into one product. Its canonical sitemap contains 476 URLs, consistently covering the wider content and deck ecosystem as well as the core analyser.
System components
What the solution is made of
Three concrete components that turn the concept into a usable system.
An explainable bracket engine
Scryfall resolution and deterministic rules show how the result follows from the cards in a specific decklist.
Suggestions with context
Recommendations are organised into clear, shareable categories instead of ending with an abstract score.
Beyond the analyser
A builder, saved decks, precons, friends, playgroups, meta features, and bilingual content turn the analysis into a broader product.
