Confound

  Official Ruling
  Confound doesn’t resolve if the targeted spell has been countered or does not still target one or more permanents that are still creatures and are still on the battlefield. Confound is different from other such spells in that it actually specifies that the spell must target a creature, not just be able to target a creature or that the spell has a certain number of targets.
