Flash an attacker out of combat at the moment it would deal damage and you get a tempo swing that a straight removal spell can't replicate: the creature survives, but the damage it was about to deal evaporates, and now there's a flying body on your side to swing back. The combat-removal effect here is a fog with a beneficiary. It pulls one attacking or blocking creature out of the fight entirely, which means it can pull back your own attacker to save it, save your own creature from a doomed block, or simply ambush a swing and leave a 2/2 flyer behind. The trade-off is that the target lives to fight another turn, so this is a tempo card, not an answer; it buys a combat step, not removal of the threat. Flash on a four-mana body is the price that makes the ambush work, letting it hold up as an instant-speed surprise the way a combat trick does, while still being a permanent that contributes after the dust settles. It sits in a long line of white flash flyers that turn the attack step into a guessing game, and the combat-removal clause is the wrinkle that distinguishes it from a vanilla flash beater: the value isn't in the stats, it's in choosing the exact moment to erase someone else's math.
