MTG Rules Guides
Free rules references for Magic: The Gathering players of every level.
Learn the Rules That Win Games
Magic: The Gathering has one of the deepest and most complex rule systems in any card game. Knowing how the stack resolves, how layers determine an object's characteristics, or exactly when a triggered ability goes on the stack can be the difference between winning and losing. These guides break down the rules that matter most into clear, practical explanations grounded in the official Comprehensive Rules.
Every guide is written for real players — whether you're a newcomer learning how combat works or a veteran brushing up on replacement effects before a tournament. We cite specific rule numbers so you can verify everything yourself, and each guide includes worked examples with real cards to show how the rules play out in practice.
All guides are completely free, with no account required. If you have a specific rules question that isn't covered here, you can always ask the Pocket Judge rules engine for an instant, judge-level ruling.
