Cemetery Reaper rulings:
2009-10-01: Cemetery Reaper grants +1/+1 to all other Zombie creatures you control, not just the ones its ability puts onto the battlefield.
2009-10-01: The creature card in a graveyard is exiled as part of the activated ability's effect, not as a cost. If that card has left the graveyard by the time the ability would resolve, the ability doesn't resolve and you don't get a Zombie token.
