Some Under/Overpowered or just random PLANT cards and some suggestions

Do feedback on whether my ideas make sense or are impractical.

Soul Patch

Should patch is underpowered. Having 5 damage, it can be destroyed by Cut Down to Size and Rocket Science, or Nibble and Slamming smackdown, or simply just destroy a plant or a Zombie with Deadly. Its armor doesn't really help too much either.

Instead:

3/7

Armored 3

Seedling

End of turn: This transforms into a random plant costing 4 or less. (Not 6, 5 is fine as well though)

Magic beanstalk

Remove draw a card function

Brainana

Winter Melon

Splash Damage 3

Great Zucchini

5/5 Remove Amphibious
