Strategies
Smelly Zombie can be considered the most "standard", yet more useful variant of the twootherDeadly zombies, due to it possessing useful qualities in terms of its strength, health, its Gravestone trait and its cost of 3.
While it has 1 extra needed to be played compared to Toxic Waste Imp, this zombie is able to wall more damage itself, unlike the other. Smelly Zombie, if possible, may be more useful than Barrel Roller Zombie for the same reason, though it costs less brains when you need to use a Deadly zombie.
In most cases, due to its trait, Smelly Zombie is more suited in attacking fighters compared to Heroes. To use this zombie well, use it on any powerful plant, such as Super-Phat Beets or Cornucopia, or any other plant that you may have trouble countering against, which you wish to quickly get rid of easily.
Thankfully, due to its buff of +1 in the 1.2.11 update, it is now able to attack 1 plants, these being Jugger-Nut, Tough Beets and Soul Patch, these plants possibly making the battle difficult for the player.
As it comes out from a Gravestone, the Plant Hero will not be able to counter this zombie entirely until the next turn, with the exception of Grave Buster, though the chances of the opposing hero having it all the time may not be common. If a powerful plant is placed on a different lane from where this zombie is, you may move it with Smoke Bomb or Carried Away. Giving healing Tricks such as Camel Crossing or Vitamin Z may help this zombie to last longer.
Giving this Frenzy can be a good idea, since it will instantly kill any plant it attacks, allowing it to attack again. This can work well against Guardian heroes especially, as you can kill any Team-Up plant they put to protect an important fighter. Boosting its health can also be a good idea. Keep in mind though, only Brain Freeze or Neptuna can use this strategy.
Counters
This zombie may be dangerous especially if it is going to face a powerful plant of yours. Including the fact that it has a bulky amount of 4, while coming out from a Gravestone. If you know that your opponent has a Smelly Zombie in their deck, take caution if they play a Gravestone zombie. If possible, use Grave Buster to get rid of it. When it has emerged, freeze it with Iceberg Lettuce, then use an offensive plant to kill it. If you are desperate to kill it, use Sizzle or Squash to aid you. Chomper's effect will make short work of this zombie.
