2 rulings from Wizards of the Coast
- 4 October 2004Corpse Dance only exiles the card if the card is still on the battlefield at the beginning of the end step.
- 1 April 2008The effect only grants Haste until the end of the current turn. If the creature somehow manages to stick around until a later turn, it will no longer have Haste.
