This deck focuses on the good amount of Gravestone Zombies that Impfinity can benefit from. There are only 3 types of zombies that aren't Gravestone out of 13 (4 if you count Mixed-up Gravedigger). Crazy Zombies with Gravestone are especially useful, such as Conga Zombie, Newspaper Zombie, and Jester. There are also common tricks to help out, and a few powerful Zombies in the late game. Mixed-up Gravedigger can easily turn the tide of battle if you can manage to keep everything alive, which should be simple. Impfinity also possesses In-crypted, which can safe your zombies in a pinch, and if Headstone Carver is on field, can boost it back again. This is especially helpful on Jesters.
This deck uses Imps to swarm the opponent and fill the field before the opponent has a chance to breathe. It also contains tricks to support and keep the damage coming. The individual is weak, but the collective is strong.
This is a deck for Impfinity which strongly relies on winning early, and dealing lots of damage to the plant hero. Most of the cards have high attack, anti-hero or strikethrough. You should be able to win by turn 10, as long as you place your zombies in empty lanes. Ignore any plants your opponent places, and focus on attacking the plant hero. You can always use The Chickening to get rid of any annoying plants.
This deck is similar to Impfinity's "Pain in the Deck" strategy deck and Z-Mech's "Stop hitting yourself" strategy deck, but still has zombies to help for the late game. It fully focuses on doing as much damage to plants as possible in order to remove them, as well as activate the abilities of zombies with the "When Hurt" ability. And all the while, Zombot Sharktronic Sub grows stronger with every dead plant. (You can't see it in the deck because there apparently wasn't enough room to show all of the cards in the deck.)
This deck is a Anti-Hero deck which is mixed with Enviroments. The Anti-Heros will strike the Plant Hero easier and meaner with Meteor Z and Laser Base Alpha. Space Ninja is also essential in this deck - he can wipe out weak plants on the field so zombies can attack your opponent directly (I recommend putting Space Ninja in Laser Base Alpha so you can kill all plants on the field).
If you don't have Trapper Zombies, I suggest you can add 1 Newspaper Zombie and 1 other Anti-Hero Zombie (Any of them) for now. This note is also for those people who don't really find Trappers useful. You can use the cards i mentioned instead.
