Train like a tournament judge.
Work through game-state scenarios, get instant feedback, and trace rulings to their sources. Practice card interactions, timing, combat, DON!! costs, Triggers, comprehensive-rule fundamentals, and tournament policy with questions checked against saved official sources. Each answer includes its cited PDF page. This is unofficial study material.
Random questions without repeats. Choose 10, 20, 30… or All. If fewer match your filters, the session includes every matching question. Review missed uses the same count across all topics and sets.
Build your practice routine
Practice gives feedback after each answer. Mock exams reveal scores and explanations after you submit. Older scores are preserved.
Main topic progress
Topic counts start with answers submitted in this version. Older aggregate scores are preserved separately. Accuracy describes past attempts, not judge qualification.
Scores by subject
Each answer counts once in every matching subject. Subjects overlap, so their totals are not added together. Detailed subject and set scores start with new attempts; older topic and overall scores stay saved.
Scores by card set
Card numbers identify sets. General rules and tournament policy have separate source groups. Questions involving several sets count once for each set.
