Strategies
With
At first, Sap-Fling may seem like a rip-off due to his low stats for 6, but his ability to make an environment to take away 3 from all zombies in it makes this plant worth it. Sap-Fling's ability can also override a zombie environment and shut down the abilities of Kite Flyer, Zom-Bats, Vimpire, Space Ninja, and Space Cowboy if they are unboosted and untouched. Sap-Fling can also nullify the Deadly, Strikethrough, and Frenzy traits on zombies with 3 or less.
Rose has a great use of Sap-Fling. Playing him while Cosmoss is on the field will give Cosmoss +1/+1. Since Sappy Place lowers a zombie's strength, Rose can also use him with Whack-a-Zombie, Chomper, or Toadstool. Citron, likewise, can use Sap-Fling's ability in tandem with tough Team-Up plants like Wall-Nut so that his opponent cannot easily bypass his defenses. He can also protect Sap-Fling from damage with Root Wall or Peel Shield, or by playing the aforementioned Team-Up plants in front of him. Nightcap can use him on Pair Pearadise, resulting in 2 Sappy Places.
Sap-Fling is also quite effective at protecting plants that may be essential for your deck's synergy, such as Starch-Lord in the case of Citron or Beta-Carrotina, or Briar Rose in the case of Rose, as Sappy Place will significantly lower the strength of zombies so that it becomes harder for them to destroy the plant, provided they are on a ground lane.
Against
When Sappy Place is made on a lane with a zombie, either move the zombie with Smoke Bomb or Bounce the zombie with Firefighter or Secret Agent. Giving the zombie +3 will counteract the ability of Sappy Place. You can also override Sappy Place with another environment, preferably cheap ones like Black Hole.
To destroy Sap-Fling, play instant-kill tricks like Rocket Science and Locust Swarm. Because of his low health, anything that does 3 or more damage, like Zombot's Wrath, can destroy him as well.
You can also punish your opponent for playing Sap-Fling due to the fact that he makes Sappy Place when he is played with Neutron Imp. Be careful when playing against Rose, as she can disable his bonus attack with Wing-Nut.
Do not Bounce Sap-Fling unless you need to, as your opponent can play Sap-Fling again and make another Sappy Place.
