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!).

The amount of damage Call from the Grave deals is determined by the casting cost . . . er, mana value of the permanent that was put onto the battlefield by Call from the Grave (even if it's not a creature at that time). In the case where no permanent was put onto the battlefield, Call from the Grave won't deal any damage.
