    User-added local evidence

    Add a competitive reference

    Record where the list came from and the context supplied by its author. This reference stays in this browser unless you explicitly copy its deck into your vault.

    Local evidence is not a verified tournament record. Riftbuilder labels it separately from generated reference shells and keeps your notes attached.
