Impfinity relies on the usage of Conga Zombies and Abracadavers early game, and focuses more on Imps later in the match. The Mini-Boss and Boss can be troublesome, as a preplaced Barrel of Deadbeards is difficult to deal with. In addition, Impfinity also has more Barrel of Deadbeards that he can use later in the match, creating a seemingly impassible wall unless you bring Doom-Shroom. The layout can be difficult, as there are 2 pool lanes and a roof lane in the middle, so heroes like Grass Knuckles can perform poor in this mission. Citron can be helpful, as he has plenty of Plants with Amphibious and Team-Up.
Electric Boogaloo uses a lot of tricks so you shouldn't bring any strong plants as he may use Locust Swarm. He has few weak zombies but with Gargantuars. Try to use cheap cards like mushrooms however he will try to get rid of them quickly. He won't attack plants with 0 strengths so bring plants like Wall-Nut, Potato Mine, etc. and surprise him by using Spineapple or turn all of them into Pineclone. Using Doom-Shroom to destroy Gargantuars. Win before turn 12th or he will likely play Gargantuars' Feast and end the game in his favor.
This mission's title is based on the saying "It's Alive!".
