Wing Puncture

• WWizards of the Coast2011-01-01
  Official Ruling
  If either target has become illegal by the time Wing Puncture resolves, the spell will still resolve but have no effect. If the first target is illegal, it can’t perform any actions, so it can’t deal damage. If the second target is illegal, there’s nothing for the first target to deal damage to. If both targets have become illegal, the spell won’t resolve.
