Professor BrainstormH Sharp Eye (created by thatpvzguy)

PvZH Brainy Icon PvZH Crazy Icon

Bullseye zombies will reign supreme when you put them in Moon Base Z. Use Lurch for Lunch and Cakesplosion to make sure that those zombies will hit the hero. The Plant Hero can't block so you don't have to worry about luck.

Professor BrainstormH The King of Dancing (created by Leoaustin24)

PvZH Brainy Icon PvZH Crazy Icon
The majority of this deck is made out of dancers. Use Lurch for Lunch and Electrician to make zombies with high strength like Disco Zombie do bonus attacks and high damage. I never had Professor Brainstorm before so this deck might not work for you.

Professor BrainstormH Science Power (created by Pmhpc)

PvZH Brainy Icon PvZH Crazy Icon
This deck is mostly composed of science zombies, which is a tribe that has various powerful effects that affect only this specific tribe. Like for example, the strength raise of Zombot Drone Engineers or the bonus attacks of the Gadget Scientists. Use this correctly and you will overwhelm your foe easily.

Professor BrainstormH The Future is Now, Thanks to Science! (created by Snapdragon717)

PvZH Brainy Icon PvZH Crazy Icon
In short, this is a simple science deck that most early players can get a hold of. The general premise is to maintain a good science deck in the mid to late game, or simply abuse bonus attacks with high attack zombies. If you can deal at least 12 damage and get to turn 6-7, you can basically end a match there if Hail-a-Copter occupies an empty lane. It's recommended to do Professor Brainstorm's quests to get some of the zombies in this deck, namely Gadget Scientist. If you do not have some of the rares, super-rares, or legendaries, replace them with more Beam Me Ups, Chimney Sweeps, Conga Zombies, and Fun-Dead Raisers.

Professor BrainstormH Trick or Die (created by Dung Dinh Anh)

PvZH Brainy Icon PvZH Crazy Icon
Simple. Tricks. And Gravestones. This deck is very efficient against unsuspecting threats like Poison Oak, Kernel Corn or The Great Zucchini due to the ability to spawn zombies during Trick Phase. Watch out for Black-Eyed Pea and Brainana though.

Professor BrainstormH Valkyrie Zoo (created by PvZTryHard)

PvZH Brainy Icon PvZH Crazy Icon
This deck is probably one of the most fun decks I've discovered and it involves a one turn kill set-up using Valkyrie. In order to do this special setup, you want to mulligan for Valkyrie, Chimney Sweep, Tennis Champ and Cell Phone Zombie. Use low health minions to boost our Valkyrie and cycle through our cards using Cell Phone Zombie, Kite Flyer, and Brainstorm's Telepathy. Barrel of Deadbeards is a great keep because it can die and boost Valkyrie twice. If you are running this version of the deck, always place the barrel to the rightmost lane so that our low health zombies can attack first before they are inevitably destroyed. Now, onto the set-up we use to kill our opponent in one turn. Keep an eye on how much health your opponent has, their block meter, their board presence and the amount of cards in their hand to determine when you should place your Valkyrie. Our tools are Teleport, in order to avoid hard removal, and Lurch for Lunch to kill a plant in the way of our Valkyrie. For example: If our opponent has five cards in hand and lane one is open, use Teleport, Valkyrie, and bonus attacks if needed, to finish them off and avoid hard removal. However, if our opponent has no cards in hand and has a side filled with plants, use Valkyrie and bonus attacks to finish them off. This will all be more natural as you play this deck more.

Professor BrainstormH Trick Question (created by GamerNerd_i)

PvZH Brainy Icon PvZH Crazy Icon
WARNING: THIS IS A VERY UNIQUE AND HIGHLY EXPERIMENTAL DECK THAT IS COMPLETELY UNTESTED. USE IN RANKED AT YOUR OWN RISK. Professor Brainstorm sure does love his Tricks. In which case, why not create a deck that’s nearly all Tricks? The only three Teammates in this deck are Paparazzi Zombie, Trickster, and Mad Chemist. Everything else is a Trick! Use them to play Trickster super early and buff Paparazzi Zombie through the roof. Call in support with Beam Me Up, Hail-a-Copter, and Gargantuars’ Feast! Mad Chemist ensures that you'll never run out of Tricks to play, and a combination of Rocket Science and crazy damage lets you control the board at any time. Creator’s note: It is a actually preferable to have max copies of Trickster and Gargantuars’ Feast. This deck has less than that to help players without access to those hard-to-get cards. If by chance you should have max of these Legendaries, replace these cards in order: Lurch for Lunch x2, Cakesplosion x2

Professor BrainstormH OTK P2W deck (created by Iamarepeater)

PvZH Brainy Icon PvZH Crazy Icon
Note: This deck was originally made by FryEmUp. Click on the link to see the deck in action. This is an extremely powerful deck. Control the early game by using Bungee Plumber and Beam Me Up. Wipe clean the field using the Barrel of Deadbeards and Fireworks Zombie combo (which also boosts the Valkyries), terminate high-strength plants with Rocket Science, and finish off the opponent by teleporting either a cheap Trickster or a 20-strength Valkyrie.

Professor BrainstormH OTK Budget deck (created by Iamarepeater)

PvZH Brainy Icon PvZH Crazy Icon
Note: This deck was originally made by FryEmUp. Click on the link to see the deck in action. This deck is is meant for players who are unable to afford the high cost of legendaries.

Keep the card count with Kite Flyer and teleport in a 20-strength Valkyrie for a surprise finisher if they managed to swat away the swarmers.

Professor BrainstormH Poor Man's OTKV (created by Camwood7)

PvZH Brainy Icon PvZH Crazy Icon
Are you a starving millenial who literally can't think of a good opening to your deck? Do you think "man, I wanna do a OTK Valy deck, but I only have, like, so much money?" Well, you're in luck, sort of.

This deck does use a few expensive cards, and one event, but you shouldn't suffer too much, as just topdecking the Valykarie and Teleport should prove to be a great endeavor.

Swarm the field with your cheap cards such as Tennis Champ or Unlife of the Party, and boost that Valykarie up, and then teleport them in! And even if it doesn't go as planned, you have backups, with great card control capability and a healthy duo of Tricksters to help in a last-resort, or in simply widdling your opponent down for the fat lady's solo of doom. And to help the Tricksters, or just general control, a good helping of bungee plumbers and rocket science will surely not steer you wrong.

Professor BrainstormH Drawing Frenzy (created by Lily8763cp)

This deck is around drawing a lot of cards to have the upper hand against the enemy, as well as a few ways to draw cards for your allies, so you are able to deal bullseye damage with Quickdraw Con Man.
