What are your favorite outside the norm Instants that have saved you?

I love Annul. Instant. 1 Blue; counter an artifact or enchantment. Simple, cheap, and effective. How many decks crumple if you block their everything-now-better-complements-my-commander big artifact or enchantment?

A runner up is Setessan Tactics. A fight effect that scales so well with the game and is a great tool for a Mono-Green deck.

I'll see y'all at the tables.
