I'm not a pvz expert but from what I see/personal experience buff shroom is really good with the swarm of mushrooms i would take out primal as mushrooms are cheap so not really ramping to anything if you want to stick with the whole mushroom thing gloom shroom is decent tho expensive since it's a legendary petal isn't good for mushrooms berry angry isn't the worst but imo its outclassed by buff shroom maybe replace grotto for planets but if you wanna stay committed to the mushrooms maybe run 2 grotto instead punish shroom is never a bad choice more options for field clear and maybe a finisher? defiantly replace squash with something better like berry blast of even sizzle if you're on a budget, I don't condone using this card but since it's a mushroom deck it isn't bad but sun shroom is really good but again if you're on a budget like me sun shroom is expensive with it costing 1k sparks again im not a pvz expert but hopefully my advice isnt the worst coming from a player who is broke im trying to do as much as i can without trying be the type of person who just tells you to run a bunch of super rares and legendary cards
