Text (VI+errata): 1/1. ; When ~this~ is put into your graveyard from the battlefield, at the beginning of the next end step, you lose 1 life and return ~this~ to your hand. [Oracle 2009/07/08]
The loss of life is not optional. [bethmo 1997/01/28]
The life loss and the return to hand both happen at end of turn as a single effect. It is not two separate effects. [Duelist Magazine #17, Page 28]
