Plants vs zombies unbalances and idea fixes

I agree with the fact plant environment are better but they have much fatier costs then zombie environments. They are also easily countered with these low costing environments that they are never guaranteed to be used. If brain vendor is so annoying why use the lot of them? Lol theyre annoying for plants thats a fact. Especially when used with final mission to further their cause or even as plain free spawn. Weed spray risky? How? Avoidable? How? They should nerf this to the point that it only affects ground lanes or actually make it risky and affect both plants and zombies alike lets see how many decks take this card after that. Camel crossing is okay not a big deal in my part its just that plants dont have cards that affect all plants with one cost. Escape through time i know it makes you wanna play as a zombie how can you not with such powerful tricks (thanks for making my point). I have since changed my mind about rolling stone, alpha station, cone zone and zombie king. In general plants dont have tricks like these to get to use before the fight begins; give plants more team up like there are gravestones, more low costing tricks that give bonus attack Or more counters for tricks that dont just involve plant effects and then i'll consider it a fair fight
