灼世劫

01/07/12

These actions are performed in order, but no triggered abilities resolve in between them and no player may cast spells or activate abilities in between them. This means that if a permanent’s ability triggers on a player losing life, that permanent will be exiled first and won’t be on the battlefield when your life total becomes 1. Leaves-the-battlefield triggers won’t resolve until you’re done resolving Worldfire entirely.

Worldfire won’t be exiled. It will go to your graveyard as the final part of its resolution.
