  This spell has a self-replacement in it . This means that if Urza's Rage is kicked, the 3 damage is replaced with 10 unpreventable damage before any other replacements can be applied. For example, you can't use Healing Salve to prevent the 3 damage before it gets changed.

  If the target for Urza's Rage becomes an illegal target, the spell won't resolve and will be put into its owner's graveyard with no effect. This is true even if its damage can't be prevented and even though it can't be countered.
