Text (UG+errata): 99/99. ; ~this~ into play. If either ~this~ card. ; more creatures. [Oracle 2009/07/08]
This creature is actually split across two cards. The above text and information is what is shown when you put both parts together. Each of the two halves is a rare card. [D'Angelo 1998/09/01]
"Both cards" means one of each half, not two of the same half. [Barclay 1998/08/13]
While the BFM is in play, it is treated as one creature, not two. While it's not in play, each half is treated as a separate creature card. [bethmo 1998/08/17] So while it's in play a Clone can copy the whole creature. [bethmo 1998/11/24]
You can put the BFM into play using Living Death, Timmy, Power Gamer, or any other effect that puts a creature into play or multiple creature cards into play at once (if both halves are present). You cannot put it into play with Animate Dead, Spatula of the Ages, or any other effect which only puts one creature card into play. [QAS 1998/09/09]
Can make "The-Biggest,-Baddest,-Nastiest,-Scariest-Creature-You'll-Ever-See" tokens with Volrath's Laboratory. They will only be 2/2. Nobody said that Volrath was perfect. [Barclay 1998/08/13]
This thing is big, making me the second largest furry creature in existence. [Garfield 1998/08/23]
If it was allowed in tournaments, you would be allowed 4 of each half in a legal deck. [bethmo 1998/09/09]
The half without a mana cost printed on it is considered to have a mana cost of the whole amount if some effect asks for that card's mana cost. [bethmo 1999/01/11] But to play the pair you only pay the mana cost once.
All tournament formats have banned cards from Unglued.
