User Dave, the vapours are no longer considered a real ailment. But I believe Fume-shroom will be of use here. His vapors are quite real and provide a distinct advantage against the right zombie opponents.
Start off with two columns of Sun-shrooms. Use Grave Busters to remove the graves and Puff-shrooms to kill the typical zombies. Get ready for an ambush.
Quickly plant one column of Wall-nuts or Tall-nuts. Do not forget to plant one column of Laser Beans or Snapdragons behind Wall-nut or Tall-nut and two columns of Fume-shrooms. Now there will not be any problems about those little Imp Monk Zombies from the graves.
When a Jester Zombie comes, now if you bring any plants that shoot projectiles, then remove it. You have read Jester Zombie's almanac, so you should know it. Remove Puff-shrooms.
Now do what you want. Remember the Cherry Bomb, use it when important. Keep using Grave Buster to remove spawned graves.
