  Scry — Look at the top N cards of your library, then put any number of them on the bottom of your library and the rest on top in any order.

  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
  If another permanent becomes a copy of a leveler, all of the leveler’s printed abilities—including those represented by level symbols—are copied. The current characteristics of the leveler, and the number of level counters on it, are not. The abilities of the copy will be determined based on how many level counters are on the copy.
• WWizards of the Coast2024-11-08
  Official Ruling
  A permanent’s level is based on how many level counters it has on it, not how many times its level up ability has been activated or has resolved. If a leveler gets level counters due to some other effect (such as Phyrexian Seedling’s proliferatelink ability) or loses level counters for some reason (such as Vampire Hexmage’s ability), its level is changed accordingly.

  Official Ruling
  The abilities a leveler grants to itself don’t overwrite any other abilities it may have. In particular, they don’t overwrite the permanent’s level up ability; it always has that.

  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.
