The good Maehv deck has 3 Prophet, 3 Gnasher, 3 Mystic/Azure, 3 Sphere, 3 Whip, 3 dispel of your choice (Shroud is better), 3 draw engine (Neko or Jammer), and 3 Desolator. Look at Deathsadvocate’s tempo Maehv for an idea of where to start.
Very difficult to create a competitive Maehv deck that doesn’t have the above (although Rescue can substitute for Mystic or Azure).
