Grass KnucklesH Power-Up Punishment (created by Lily8763cp)

PvZH Mega-Grow Icon PvZH Guardian Icon
This deck is focused mainly on powering up plants in many different ways. Using Torchwood and The Podfather to power up pea plants' attack, using Smackadamia to increase nut-related cards' health, and using Spineapple to add attack to plants otherwise lacking the ability to attack. Grow-Shroom and Fertilize will also increase the stats of other plants on the field, as Potted Powerhouse gains a boost on each time another cards' stats are increased.

Grass KnucklesH I'm All About That Bait (BUDGET) (created by TheMajesticStork)

PvZH Mega-Grow Icon PvZH Guardian Icon
Set up a strong early game with Health-Nut, which gives you a threatening 4/4 for only 3 sun. Boost it with Photosynthesizer and Grape Responsibility. Turn on the pressure on your opponent. As it grows, they'll be baited and you'll have time to set up your real trap - the Re-Peat Moss. As you're boosting the Health-Nut with your tricks, your Re-Peat Moss will be doing loads of bonus attacks. Put it in a Coffee Grounds then strike with a Vegetation Mutation. Have a good laugh later.
