3 rulings from Wizards of the Coast
- 4 October 2004This is not damage prevention or redirection. It actually is life gain and newly dealt damage.
- 4 October 2004You can't use Simulacrum on Loss of Life, just damage.
- 1 August 2008Simulacrum is the source of the damage. If an effect needs to know a characteristic of the damage's source, it will see the damage coming from Simulacrum.
