  Official Ruling
  Playtest cards aren’t legal for play in any tournament format other than Mystery Booster Limited formats. On the other hand, we expect they will spice up a wide variety of non-tournament games (as long as everyone’s on the same page about using them!).

  Official Ruling
  A conjured card’s owner is the player who was instructed to conjure it.

  Official Ruling
  For many playtest cards, you’ll need to make a generous assumption that basic game rules would be updated to allow them to work. The Mystery Booster 2 Playtest Card Notes section (reproduced here in individual Gatherer rulings) provides guidance for fitting these cards into the existing rules structure.

  Official Ruling
  Playtest cards use a modified version of game symbols, such as and . These modified symbols should be treated as the standard symbols during play.

  To conjure a card in a game of tabletop Magic, use the Gatherer card database at Gatherer.Wizards.com to find the official text for the card you’re conjuring. Then put the appropriate conjured card into the appropriate zone.

  Official Ruling
  You can represent conjured cards using objects from outside the game so long as the game state remains clear and understandable to all players. You might need to get creative. For example, while a conjured card is in a public zone, you can represent it by writing on a piece of paper or using some kind of token. But if a conjured card is put into a hidden zone, you must add an object to that zone which, while face down, is indistinguishable from other cards in your deck.
• WWizards of the Coast2024-11-08
  Official Ruling
  You do not need to own an actual copy of a card in order to conjure it, and a conjured card does not need to obey format legality or deckbuilding restrictions. For example, in a game of Mystery Booster 2 Limited, Toralf’s Disciple can conjure Lightning Bolts into your deck, even though the card Lightning Bolt isn’t found in Mystery Booster 2 and isn’t normally legal in the Limited format.

  Official Ruling
  Conjured cards are not tokens. Treat conjured cards just as you would treat regular cards. They can move between zones just like any other card and continue to exist for the duration of the game. At the end of the game, make sure to remove all conjured cards from your deck.
