Azorius Skyguard

The static -1/-0 anthem is what separates this from a plain evasive body: shrinking every opposing creature's power turns the flying, first-strike attacker into a piece that also plays defense, since a wall of shrunken attackers means favorable blocks and stalled races. That debuff shows its hand best in the air, where flying and first strike combine to let it eat opposing flyers cleanly, but the -1/-0 reaches the whole board, blunting go-wide aggression by a point at a time. Six mana buys a modest 3/3, so the pitch here is not the rate on the stat line; it is the ongoing team-wide power reduction that keeps working whether the card is attacking, blocking, or sitting back. As a design it belongs to the small family of white-blue fliers that bring a passive combat tax with them rather than a one-shot effect, the kind of card built to grind out a defensive board state and then close in the air once the ground is neutralized.
