He believes good things come in small packages. And in threes.
Impfinity swarms the board with a horde of Zombie Imps that multiply almost as fast as he does. Imp Commander and Toxic Waste Imp helps the Imp army gain the ultimate advantage.
Impfinity's class combination of Sneaky and Crazy zombies makes great synergies. Both of these classes are great at dishing out damage, but fare very badly after getting hit most of the time. Much like Crazy Dave says when Impfinity is first fought against, it's obvious that Impfinity's strategy is swarming the opponent with large numbers of cheap, hard-hitting zombies for a quick knockout. As Impfinity, the player must make sure the opponent is defeated quickly as Impfinity will not fare well late game due to having mostly cards that have to make an impact before they're hit even just once, as cards in Impfinity's grasp that can last are mostly rare and expensive to some degree.
Impfinity has access to zombies with Deadly, Anti-Hero and even Amphibious traits, which all have great synergy with each other and allows him to roll with the aforementioned strategies. This is not to mention his access to The Chickening, Unlife of the Party, and Cakesplosion, all of which can allow the player to rev up the aggression and swarms Impfinity dearly needs. Imp-Throwing Gargantuar, Walrus Rider and Imp Commander should be reserved for when Impfinity is in a disadvantage of fair size, usually when Impfinity himself is low on health, or running out of other cards and the match has lasted a while. In addition, Impfinity has access to the most pirate zombies in the game, only missing Shieldcrusher Viking. So a good strategy for Impfinity would be a pirate deck, although pirate decks are usually reliant on cards such as Swashbuckler Zombie and Imp Commander, which can be very difficult to be kept alive and protect throughout the match.
Impfinity can also run a mean Gravestone deck if performed correctly. His access to Crazy Gravestone zombies such as Newspaper Zombie, Jester, and Exploding Imp allows him to pressure his opponent with Headstone Carver. In-Crypted is also in Impfinity's superpower pool, which can be used to his advantage. If late game occurs, Gargantuars' Feast and Zombot Sharktronic Sub can be good options to wipe his opponent out.
That's a plus, but Impfinity has problem with drawing cards. He has to use Super Stench and In-Crypted, both of which can only be used once per game, to draw a card. So it is best for Impfinity to keep an eye on the cards in his hand, otherwise there will be nothing left for him. In case of Imp decks, however, this should not be any problem thanks to Imp Commander, who lets Impfinity draw cards by having Imps hurt the plant hero.
Impfinity is somewhat simple and obvious, yet adrenaline-inducing. Among the biggest, earliest, and easiest means of giving him a hard time is to use plants and tricks that damage multiple zombies at once in a particular area, or plants with Splash Damage such as Lightning Reed, Snapdragon, and Winter Melon can sabotage most, if not all, of Impfinity's glass cannon teammates that are on the lawn. Kabloom heroes can also use Sour Grapes or Kernel Corn to take out some of Impfinity's low health zombies. Setting up, stalling, blocking attacks, and taking advantage of the frailty of most of his zombies (all of which are tactics that can quickly exhaust all or most of Impfinity's cards) can also guarantee a win against Impfinity if done correctly.
Fighting Impfinity with a Gravestone deck, however, is a whole different story. He can easily destroy weak plants with Conga Zombie, try and abuse Newspaper Zombie by moving him around and using Headstone Carver with him, and use other tanks or glass cannons. Impfinity also has a lot of Gravestone zombies that cost 2 or 3 brains, so it can be unpredictable to what zombie will appear out of a gravestone. His assortment of Gravestone zombies is very unpredictable, rivaling Neptuna's Gravestone zombies. For example, on turn 3, Impfinity can use either a Jester, Stealthy Imp, Exploding Imp, Smelly Zombie, Abracadaver, or Line Dancing Zombie, all of which are either useless with a plant in its lane or useful with a plant in its lane. In short, Impfinity can be real threatening if the player does not catch onto their strategy. In these cases, it's best to watch what you place, defeat all of his zombies quickly, and try and exhaust all of his cards, as in the late game, Gravestone decks start to fall apart if cards are not abundant.
