Cleaver Blow

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.

There are 64 different ways to cast Cleaver Blow using its multicleave ability.

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.

Multicleave is an optional additional cost.

If you paid Cleaver Blow’s multicleave cost, that spell doesn’t have any of the text in the chosen set (or sets, as appropriate) of square brackets while it’s on the stack.

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!).
