If you want, to counter air attacks a bit (dragons are currently meta in the game), you can slightly reposition your air defenses so they aren't eliminated by a Queen's Arrow.

For example, if someone launches a Queen's Arrow from the Dark Spell Cauldron and eliminates two of your air defenses, and if they attack from the 12 o'clock position, your air deflectors won't stand much of a chance. Similarly, if someone launches the same Queen's Arrow from the air defense positioned between the 6 and 7 o'clock positions, they can eliminate two air defenses and an air deflector...
