Ideas for Cards in Plants Versus Zombies Heroes

I enjoy creating and balancing cards in card games, and I love the idea of a Medieval flavored PVZ Heroes card set. So I decided to invent some cards that would go into it. I do not know of a way to create PVZ Heroes-style cards, so I made them in a Hearthstone card generator.

This is a Professional Zombie in the Beastly category. It is Uncommon. You can play the Peasant Zombie over top of another zombie (Zombie Evolution), or play another zombie on top of the Peasant Zombie (Fusion), to get small buffs. It is designed to work well in decks with large swarms of zombies. I Think the Peasant Zombie is pretty well balanced for an Uncommon card. It is not intended to be incredibly powerful, but I think it’s still fun.

This is a Professional Zombie is in the Hearty category. It is Super-Rare. It’s Evolution effect is intended to mostly be useful in decks with low cost-zombies. I decided on making the Conehead Peasant Super-Rare, because of how it can give other zombies played on it Armored 1 while costing only 1. Also I want to clarify that Armored would not stack with any other Armored effects.
This is an Environment in the Beastly category. It is Rare. It feels right at home in the Beastly class.

THIS WAS MY OVERPOWERED FIRST DRAFT OF “ZOMBIE HAMLET”
My first Draft of Zombie Hamlet was actually pretty OP and difficult to counter. Upon closer inspection, I realized that this earlier draft would be horribly un-fun to play against. Infinite amounts of free Peasant Zombies every turn can permanently close off this lane for the Plant team. Also the Plant team can’t just ignore this lane, as the Zombie in it constantly grows bigger. So I decided to remove the Zombie-making aspect of this card.
