Strategies
With
Jack O' Lantern is a very devastating plant if kept alive, as its ability activates every time it attacks due to its Strikethrough trait. You can take advantage of this and use tricks such as Plant Food and Espresso Fiesta or environments like Coffee Grounds to make it do bonus attacks as Chompzilla to quickly snowball its strength, or just directly boost its strength as Chompzilla or Solar Flare.
However, because its ability only increases its strength but not its health, Jack O' Lantern can be overwhelmed easily. Wall-Knight can use Team-Up plants to protect him. Chompzilla can also boost it's health with tricks.
Speaking of Chompzilla, she can use it to boost Potted Powerhouse while still in her hand.
Keep in mind that if your opponent blocks Jack O' Lantern's attack, its ability does not activate. Therefore, it is a good idea to have another plant or damaging trick to trigger the block beforehand, although this may put it at risk of superpowers such as Electrobolt.
Against
Jack O' Lantern is a big threat, so it should be dealt with as soon as possible. Since it has the Strikethrough trait, simply blocking it with a zombie isn't enough. It must be destroyed, otherwise it is going to mass up strength, which is never good.
Any zombie with 3 strength can destroy it easily, unless its health has been boosted. Rolling Stone can be played when it hasn't gained any strength, while Rocket Science, Cut Down to Size and Locust Swarm can be played when its strength becomes too much for you to handle.
Additionally, you can reduce this plant's strength with Landscaper or Nibble, rendering it unable to attack and boost itself. However, beware when playing against Solar Flare or Chompzilla as they have tricks such as Berry Angry and Fertilize to boost it again.
However, if you think that you are able to block its attack, you do not need to worry since his ability only activates when he does damage to you.

In addition to both it and Trick-or-Treater being the first Halloween event cards, they are also the first event cards to ever be introduced (in Jack O' Lantern's case, that makes him the first event plant card ever).
