"My ruling is final. Order is upheld. Justice is done."
Illus. Matt Stewart

10/1/2012: You must be able to target a spell to cast Fall of the Gavel.
10/1/2012: If the target spell is an illegal target when Fall of the Gavel tries to resolve (perhaps because it’s been countered by another spell), Fall of the Gavel will be countered and none of its effects will happen. You won’t gain 5 life.
