It's not as simple as a Squash though, is it. First, it requires you to actually have a zombie to use it on. Second, that zombie has to be in the lane of the plant you want to kill, unlike Squash, which can kill any plant no matter which lane it's in. Needless to say that it won't work if said zombie is frozen, if the plant you want to kill is behind another plant, or if the plant you want to kill is immune. You also have to hope that the zombie you want to target isn't killed before the tricks phase. Barrel of Barrels may be an uncommon card, but Squash is a basic card. It is simply not a '1-cost kill anything' like you say it is.
Barrel of barrels, is too cheap. Squash costs 5, and your unlikely to win a game by filling your deck with the 4 squash that you are allowed to have in a deck. Why? As it does no damage to the hero, but if you have to 5 sun to play it you won't be able to play a plant as well. Where as barrel of barrels you can end up with endless amounts of these, and they only cost 1.
