Strategies
With
Bonk Choy can be considered as the plant equivalent of Tennis Champ. However, Bonk Choy has higher base strength than Tennis Champ, while its extra strength is lower than its zombie counterpart. The strategy for Tennis Champ mostly works the same for Bonk Choy; only use it in the early rounds, as it will be near useless in later rounds.
Bonk Choy is an excellent counter against zombies that cost 1 brain and have 3 health or less, such as Dog Walker, Headstone Carver, and Arm Wrestler. The only possible 1 brain zombies that can survive Bonk Choy's attack are Cat Lady and Planetary Gladiator, but only if they are unharmed.
Bonk Choy can also be used to easily boost Potted Powerhouse as its ability guarantees a strength boost, and due to its cheap price, it is easier to spam.
Because its ability only lasts one turn, you can use Rescue Radish to replay it again so that it can activate its ability again as Green Shadow.
Against
This plant's high strength and low health means that it is a relatively easy to destroy glass cannon. Because of this, expect the plant hero to use this as a cheap way to destroy an important zombie with 3 health or less. Direct damage effects such as Conga Zombie, Fireworks Zombie or Bungee Plumber, and stat-reducing abilities like Nibble, Pied Piper or Acid Rain are all excellent options to use against Bonk Choy. However, early-game, your opponent may play Bonk Choy away from a zombie to do 3 damage early. In this case, the only method of dealing with it is to read the opponent's first turn and then play a trick like Nibble or Bungee Plumber.
