Intangible Vibes

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.

After a creature leaves the battlefield, it does briefly enter whatever zone it was put into before it ceases to exist. For example, a creature that’s put into a graveyard and then ceases to exist still triggers “Whenever a creature dies” abilities.

Playtest cards use a modified version of game symbols, such as {T} and {W}. These modified symbols should be treated as the standard symbols during play.
