MAGIC: THE GATHERING
If it's not your turn, you may exile a blue card from your hand rather than pay this spell's mana cost.
Counter target noncreature spell. If that spell is countered this way, exile it instead of putting it into it's owner's graveyard.
"Free" counterspells, such as Force of Will, have often been relegated to Legacy and Vintage. With the release of Modern Horizons, Modern control decks now have access to Force of Negation, so they can tap out for a planeswalker spell without fear.
