The cleanest expression of the spells-matter common: an evasive body whose entire value proposition is that it grows when you do the thing your deck already wants to do. A 2/1 flier dies to a stiff breeze and threatens almost nothing on its own, but each noncreature spell turns it into a 3/2 in the air for a turn, and a deck stocked with cheap cantrips and burn can chain those triggers across a single swing. That is the deal prowess offers throughout this color: the creature is not the engine, it is the payoff for the engine. The Bird's job is to convert a hand full of card-advantage and removal into a clock without asking the pilot to commit a card to do nothing but attack. Flying is the load-bearing keyword here, not prowess; a ground creature growing for a turn often just trades into a blocker, but an unblocked flier banks every pump as real damage on the way to the face. It is a creature that punishes a tempo-light opponent precisely because the spells it leans on are doing double duty, interacting with the board while also feeding the attack.
