Grave Buster is a premiumuncommonplanttrickcard in Plants vs. Zombies Heroes, and a member of the Guardian tricks. It costs 2 to plant and has the purpose of destroying a zombie gravestone, preventing their effects from triggering and destroying the zombie. The destroyed grave will expose the zombie under it for a few seconds before the zombie destroys itself.
This card is ideal for any Guardian deck, as it can easily take out Gravestone zombies, which most of those zombies tend to be dangerous, such as Rodeo Gargantuar or Jester.
If possible, try not use a Grave Buster immediately upon seeing a gravestone, as certain gravestone zombies are considerably manageable, such as Smelly Zombie or Stealthy Imp, mainly due to their low amount of strength or health, unless your plant hero is at low health, where you can use it on any gravestone present as a last resort. Try to get a basic idea of what kinds of gravestone zombies are present in the zombie hero's deck, as you may know when to use it.
This trick is a great counter against Headstone Carver and Tomb Raiser Zombies, as Headstone Carver's boost to the emerged Gravestone zombie will be useless, since the gravestone will be destroyed. Tomb Raiser Zombie's spawned gravestones can be managed easily with a use of this trick.
A good way to not misuse the card on a weaker targets is to pay close attention to how many brains are being used for that Tombstone. Like above, Smelly Zombie and Stealthy Imp cost about 3 brains, and they're quite manageable, but then there are Gravestone zombies that are very powerful, which are expensive, so like said before, pay close attention to brains being used.
Against
Be aware that only Wall-Knight, Spudow, Citron, and Grass Knuckles can use this trick, meaning that you don't have to worry too much about this when fighting against other plant heroes.
