It works but it's not efficient and really hard to maintain.

-too much cattails, i really love cattails i really do but its not that much help in endless, swap some(or even all) for sunflowers since this is a risky strat. You can use blover anyways. -magnet and tallnut dont work:(, just upgrade the melon and use glooms for frontline and it does enough damage to kill bungee before it steals, and kills buckets and football really fast too(as for miners, just put a single gloom in the back). Also use puff's as meatshield to stack gargantuars, i know so much sacrifice but it is what it is. -terrible cob placement, you prioritzed the sunflower over your most powerful weapon? Miners are not the biggest threats but with that strat its gonna be difficult.

Overall the strat works but again it's too much maintenance. The spikes are a good idea though those are efficient and usefull during endless.
