There // They're // Their

2024-11-08 Each split card is a single card. For example, if you discard a split card, you’ve discarded one card. If an effect counts the number of instant and sorcery cards in your graveyard, There // They’re // Their counts once, not three times.

2024-11-08 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.

2024-11-08 If an effect allows you to cast a spell with certain characteristics, consider only the characteristics of the spell you’re casting. For example, if an effect allows you to cast an instant or sorcery spell with mana value 2 or less from among cards in your graveyard, you could cast There or They’re this way, but There is right out.

2024-11-08 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!).

2024-11-08 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.

2024-11-08 This split card has three names. If an effect instructs you to choose a card name, you may choose one of those names, but not all of them (though you might want to write it down and not just say it out loud).

2024-11-08 This split card’s characteristics are a combination of its three thirds while it’s not on the stack. For example, There // They’re // Their has a mana value of 6 while it’s in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can’t find There // They’re // Their.

2024-11-08 To cast this split card, choose one of its thirds to cast. The characteristics of the thirds you didn’t cast are ignored while the spell is on the stack.
