When can notes be made regarding a player's draft?

In the context of Magic: The Gathering draft events, players are generally allowed to make notes exclusively after the deck construction phase has been completed. This is to ensure fairness and prevent any potential disruption or advantage that could arise if players were taking notes during the drafting process. The drafting phase involves active decision-making as players select cards, and allowing notes at that time could influence strategic choices or give an indication of a player's card preferences to their opponents.

After players have completed their drafts and moved into deck construction, they can then begin taking notes to help in building their decks or in preparing for their matches. This standard fosters a more equitable environment while maintaining the integrity of the drafting process.
