Weed Spray is unbalanced

Not a cheap deck but here's my Wall Knight I played almost only Wall Knight well into the mid 30s. After that I admit I struggled pretty hard with him. The key with Wall Knight is getting into the late rounds. It's been a while but I believe I was using a couple Wall nut bowling cards instead of Soul Patch. Weed spray is tough to get around but I didn't see it that often. Gaucadile is one of the best cards in the game in my opinion. It will take out most of the best cards. Mirror nut is a must. Get more than one on the board at a time and it's typically a game changer. Especially if you get someone foolish enough to play the chickening. It's awesome when you have a full board of nuts and a couple of mirror nuts and someone drops that. If you make it to round ten and have a Wall nut bowling in your hand, more often than not, game over. The problem I found after 35 ish you run into a ton of Professor Brainstorm. The problem with him even more so than others is if you get to the late rounds, he has too many ways to finish you off. Use jugger nut instead of pismashio. Jug will kill one attack zombies without taking damage. Experiment with the flower plans as well. Mix briar rose with power flower and poppin poppies to give people fits. Morning glory is not a bad play either because it will take out low health zombies early and be immune to weed spray late. The key for me was always blocking and rarely playing in an open lane until larpter in the game. Another key for me was trying to always use all my sun if possible every round unless I thought a weed spray was on the way.
