Text (UG+errata): If you control no cards in play other than ~this~ and have no cards in your hand, you win the game. [Oracle 2009/07/08]
If you have six of these in play under your control, and you answer a general knowledge question correctly, you win the game. [Barclay 1998/08/13] In addition, five of them have to be different colors and the last one must be colorless. [DeLaney 1998/09/10]
If you cast the last card in your hand, you can win while the card is on the stack waiting to resolve. [TomHa 1998/09/15] It's cheesy, but true.
