Azorius Tempo leans on fliers (Momo, Sage of the Skies, Starfield Shepherd) and artifact mana (Springleaf Drum), so Cathar Commando is a flash body that can sacrifice to destroy Springleaf Drum or Seam Rip, which gets back whatever Seam Rip exiled. Ghost Vacuum exiles Daydream and Practiced Offense from their graveyard so they can't be flashed back, and in the late game it can sacrifice to return any creature cards it exiled as 1/1 fliers. Goldmeadow Nomad and Aunt May can't block evasive fliers and don't contribute enough pressure, making them the clearest cuts; keep the rest of the core intact since the lifegain plan still outgrinds their incremental card advantage.
