Since Wall-Knight starts with +10 health and an Uncrackable superpower , be prepared for a long fight ! Neptuna will be the best hero to use against Wall-Knight since she has acces to a lot of zombies with the Amphibioustrait that will be able to to deal a lot of damage on the water lanes, she also has acces to Weed Spray which will be able to take out most of the plants Wall-Knight plays but Neptuna also has acces to a lot of zombies with the Deadly trait which be able to take out the plants with high health. Since this fight will last for a long time, heroes with acces to cards that can heal them or their zombies will be more than useful since that fight will drag on for a long time. However if you ever use Neptuna, watch out for the Grave Buster card since it will destroy any zombies with the Gravestone trait while it is in a Gravestone. If you use Neptuna for this mission, try to win as fast as you can since she won't fair well in the late-game because of her lack of healing cards and ways too draw cards. The only ways to draw cards would be to either use In-Crypted or the Imp Commander with other Imps synergies. Instant Removal cards will also cause a problem, however Defensive End will be able to slow down the use of plantstricks.
