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 won’t resolve and none of its effects will happen. You won’t gain 5 life.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
