Strategies
With
Doing 4 damage to every single zombie on the field, Kernel Corn is a complete upgrade to Sour Grapes, and Cherry Bomb as well if there is an empty lane to play him.
When your opponent attempts to swarm you with zombies, play Kernel Corn to wipe out or severely damage your opponent's zombies for himself and your other plants to finish off the weakened ones and hit your opponent.
If you are playing as Nightcap, you can play Rescue Radish to Bounce Kernel Corn and let you replay him later on. If you are playing as Solar Flare, you can play this earlier by making excess sun.
However, despite him already having good raw stats, Kernel Corn is not as good at handling single threats on his own, so he becomes less effective if your opponent focuses on investing on a single zombie. He also has a hard time when your opponent fills the field with tougher zombies, such as Valkyrie, so you should be careful about when you should play him.
The two environments that suit Kernel Corn well are Pair Pearadise or Venus Flytraplanet. Pair Pearadise makes another Kernel Corn, doubling his destruction if needed, while playing him in a Venus Flytraplanet will allow you to recover up to 20 health, resetting it in the optimal circumstances. However, the Venus Flytraplanet combo is only possible as Solar Flare.
Against
Kernel Corn is a very dangerous plant, as he can demolish your defenses and your hero alike. Try playing instant-kill tricks such as Locust Swarm, Cut Down to Size, or Rocket Science, or Deadly zombies to get rid of this plant.
If his ability is what you fear the most, having either high-health or Armored zombies on the field lessens the harm. If you want your zombies to be unaffected by his ability, you can play Gravestone zombies or Mixed-Up Gravedigger, or sneak some in with Teleport.
It is strongly recommended not to Bounce this plant because your opponent can replay him again, possibly wreaking havoc once again on your already-weakened defenses.
