How to resolve a conflict
Use the effective Comprehensive Rules and current Oracle card text for a rules question. A dated bulletin summarizes planned changes. Product guidance supplies release and format-legality dates. Those dates serve different purposes.
Corrections
Contact the site maintainer on GitHub with the affected page, the sentence, and an official source explaining the correction. Avoid including private deck lists or account information. Rulebreak Notes is an independent explanation, not an official rulings service.
