Text (LE): 4/3. ; Morph {X}{B}{B}. ; When ~this~ is turned face up, all creatures get -X/-X until end of turn.
The trigger occurs when you use the Morph ability to turn the card face up, or when an effect turns it face up. It will not trigger on being revealed or on leaving play. [Legions FAQ 2003/01/23]
The X in the ability has the same value as the X paid in the Morph ability. This is pretty easy to derive since there is no other source of X. [DeLaney 2003/03/19]
