Strategies[]
With[]
This trick faces competition against Scorched Earth and Weed Whack. Scorched Earth matches its standard ability, is often played early game, and can affect all zombies on the ground. Weed Whack is essentially this trick at full power. However, these superpowers can only be used once in a match, while you can put up to 4 copies of this in your deck, and Wall-Knight has no access to said superpowers anyways. Be wary, however, it will not work on amphibious Zombies, some of them being dangerous threats like Space Cowboy.
If you want to put these in your deck, take advantage of cards that can destroy zombies only under a certain amount of strength, such as Whack-a-Zombie and Chomper, as well as sun-producing plants like Primal Sunflower and Twin Sunflower. They can be used to reduce the strength of zombies like Kite Flyer, who activate their abilities when they do damage, to completely nullify them.
Against[]
While Water Balloons are uncommonly seen in multiplayer games and face competition against said superpowers, remember that your opponent (if they have them in their deck) can make lots of sun, then use them to severely drop your zombies' stats or destroy them. AI opponents seem to use this a lot too, so beware. You can use boosting tricks to negate or lessen their effect as well. As Water Balloons are a trick, you can also use Defensive End to make it harder for your opponent to play them. If you are using Beastly or/and Sneaky classes, which have amphibious Zombies like Space Cowboy, Toxic Waste Imp and Synchronized Swimmer, they are completely immune to this trick due to the trick not working on the amphibious trait.
