if you want to make nut decks good

The thing with nut decks is you have to pay attention to what the other player is doing and it also helps to have an idea in your head what cards they have at their disposal. It’s not always a bad thing to have them whipe out your wall nut with say rolling stone early (which many will do if you throw it out there on turn one) because that means later when you play pecanolith the chances of them having another rolling stone are less. Also, if you see them not playing anything in the first phase especially on turn three plus, don’t load up the board with sub two attack plants on your turn. It’s ok just not to play sometimes. More often than not with Wall night you want the game to last longer so you can play your most powerful cards, I was disappointed when I saw that GoNuts wasn’t going to fit into Wall Knights deck though. Overall I would agree that he could use a couple more good cards to help him keep up at higher levels. You don’t see many Wall Knight players at high level ranked. 

@UnholyJuggernaut I was only advising you as to how to play around weed spray. Obviously that would not be your whole deck, please use basic intuition.
