With
This is an incredibly powerful trick, as it will turn all of your zombies into more powerful zombies. Make sure to have lots of cheap, disposable zombies to make full use of this trick like s or s. This not only makes a lot of powerful zombies but also increases the chance for a powerful zombie to finish the game. However, keep in mind that if you already have some expensive zombies on the field, this trick may end up making them weaker. But still, you can end up getting powerful zombies like Zombot 1000, Cryo Yeti, or, so this trick is definitely worth it in most situations. But be careful if you are facing a hero and Mixed-Up Gravedigger is made from this trick, as your opponent can simply play  to destroy them much more easily. Also, be aware that it can make weaker zombies like or Gadget Scientist.

Since this trick affects all zombies on the field, it works well with any zombie hero that can play or make many zombies at once. An example would be Professor Brainstorm, who has access to cards that make other zombies like and. Since and Huge-Gigantacus also lead the  class, they can swarm Imps to improve this trick's efficiency. They can even play Mixed-Up Gravedigger to prevent all of your zombies from being destroyed by protecting them until you can play Bad Moon Rising with the exception of Grave Buster and Cool Bean with Winter Squash.

You can pair this with Zombology Teacher to make this trick cheaper, though only Rustbolt can use her normally, or ramp up this card quickly using cards such as Cryo-Brain, Gentleman Zombie, or Medulla Nebula which all Brainy heroes have natural access to. Speaking of Medulla Nebula, you can play Brain Vendor on Medulla Nebula on turn 4 to easily play Bad Moon Rising very early. Take note that Gargologist does not benefit this trick despite the trick having a picture of a Gargantuar.

This trick can also be used to reduce the impact of The Great Zucchini, turning all your weak 1/1 zombies into highly dangerous zombies.

Against
If your opponent is a Brainy hero and you see them saving 7 brains, there is a high chance that they will most likely be playing this trick. Try to remove as many zombies as possible so they are fewer powerful zombies to work with. As a last resort, use Brainana to prevent them from playing this for a turn, or Forget-Me-Nuts or Dark Matter Dragonfruit to increase the cost of this trick. is handy for taking out most of the transformed zombies. However, you will not be able to react to it the turn it is played. So you can only prepare for the zombies that this trick will make since zombie tricks are played after plants are played.

Trivia

 * It is the most expensive event card in the game.
 * Even though the card has a picture of a Gargantuar, it is not in the Gargantuar tribe.
 * On rare occasions, this may cause zombies whose ability does direct damage like Flamenco Zombie to do more. For example, having Binary Stars and Flamenco Zombie on the field is supposed to do only 8 damage but would sometimes do as high as 13 damage instead, this is due to Binary Stars' ability are programmed to affect zombies permanently while giving them the permanent 2x bonus, then stacking it up to a 4x with the normal ability.
 * It is the third zombie event trick in the game.
 * On the sprites, an Imp is shown despite not being seen on its card.
 * However, an Imp may be rarely shown on the animation when it is played.
