With thousands of cards across decades of sets, genuinely novel rules interactions still turn up regularly, even in a game this well-established.
Why ambiguity happens at all
Card text is written to cover expected situations clearly, but the sheer number of cards means unusual combinations occasionally produce genuine ambiguity about which effect takes precedence or how two rules interact.
Rulings exist beyond just the tournament floor
Judge rulings are officially binding at sanctioned events, but they're published and searchable, making them a genuinely useful reference for resolving the exact same disputes in casual home games too.
The general resolution principle
As a rule of thumb, more specific card text overrides more general game rules, and effects typically resolve in the order they're printed or triggered — understanding that principle resolves a surprising number of disputes without needing to look anything up.
