Text (TO/9th/10): 4/4, Flying. ; Whenever a creature dealt damage by ~this~ this turn is put into a graveyard, put a +1/+1 counter on ~this~.
Gets counters when creatures go to the graveyard. If it dies at the same time as a creature it killed, it does not get the counter. If it regenerates or otherwise lives past the creature going to the graveyard, it gets the counter. [bethmo 1994/06/01]
Does not get a counter if it damages a creature and that creature's permanent is no longer a creature at the time it is put in the graveyard. [WotC Rules Team 1997/06/01] [Duelist Magazine #19, Page 31]
Extended tournaments (see Rule 913) banned this card from 1999/10/01 until 2002/03/01, when it was put back into print.
