Strategies
With
Despite this trick being able to heal you, there are not many instances in which you would plan to use this solely to heal, but rather take out, or nullify a threat that has either 1 strength, 1 health, or both in the early to mid-game. However, despite its healing ability being rather minor, it should not be disregarded either, as it could easily split the difference between victory and defeat, and should be taken into account.
Take note this only degrades a plant but does not do damage, so you cannot play Evaporate to destroy it afterwards.
Against
Nibble is a very cheap trick that is able to mess up your plants by lowering their stats so that they fail on destroying the target, or surviving the attack. Fortunately, a stat-boosting card can easily negate or lessen its ability.
A plant that is basically immune to this trick is Black-Eyed Pea, as its ability negates Nibble's ability. However, Nibble can destroy it if its health has been knocked down to one.
