Martyrdom rulings:
2004-10-04: If the target stops being a creature, you can’t redirect damage to it until/unless it becomes a creature again.
2004-10-04: If the target creature is not still on the battlefield when the damage is to be redirected, the damage stays where it is.
2004-10-04: Can be used to redirect damage from that creature to itself. This has no particularly useful effect.
