The question “when does set 1” is too vague to answer accurately without more context. It could refer to many things, such as a card game set rotation, a video game season, or something else entirely.
What is needed
Please clarify at least one of the following so the answer can be precise:
- The game or system (for example: Magic: The Gathering, One Piece Card Game, TFT, Lorcana, etc.)
- What you mean by “set 1” (first expansion, first season, or a specifically named set).
- What event you care about: release date, end date, or rotation/when it becomes illegal in a format.
Once you specify the game and what you mean by “set 1” and “when,” a concrete date or rule can be given.
