Rules Judge

Ask the Rules Judge a rules question in plain language — or snap a photo of the board — and it answers grounded in the Comprehensive Rules, streaming its explanation with tappable citations to the exact rule numbers, so you can verify every claim at the source.

The Judge lives inside Rules (the tools row → Rules → the "Ask the Rules Judge" card at the top).

• Handles interaction questions, timing, layers, replacement effects and the other 1 AM classics.
• Tag cards with @ — type @force of will anywhere in your question and an autocomplete pins the exact card, so the Judge reasons about the real card text, not its memory of it.
• Multimodal — photograph the table and describe the question; the Judge reads the cards in the image.
• The cards the Judge looked up appear as a thumbnail strip under the answer — tap one to open it.
• Every answer cites its rules; tap a citation to open it in the browser.
