Leap of Faith

Two protective effects stapled onto a single instant, and the combination buys options that neither piece grants alone. The damage prevention is the durable half: it shrugs off burn and combat damage alike, so a creature that resolves this walks out of any fight or any direct-damage answer unharmed. The flying clause does the offensive work. Granted before blockers, it lets an attacker sail over a ground defense entirely; granted to a blocker, it lets a grounded creature catch an incoming flier it otherwise could not touch. That second mode is the wrinkle that lifts it above a single-target fog: a plain prevention trick only ever defends, while the air-access rider can also push damage through or reach up to swat a flier on defense. The catch is the scope. Prevention only stops damage, so it does nothing against destruction, exile, sacrifice, or counters; a removal spell in response leaves you down a card and a creature with the trick wasted. White has a long bench of one-creature protection instants in this vein, and this one's pitch is the modest premium you pay for the flying. Held up, it reads as both blowout and bluff: the opponent has to respect an ambush in the air and a creature that survives whatever you point at it, and has to play around both lines without knowing which one is coming.
