I suggest not giving them rarities, because exactly like said the plague scientist the first thing that crossed my mind was common...too powerful. And I think that it would be better to see the card dor what it is, not having to rank it(we all do it and don't even realize most of the time)
Unless that is part of the discussion you intended on...
That being said, the pole vaulter and zomboni are awesome! Made my day, without a doubt. I'm still grinning like a meatball, all by myself lol. I totally agree with the veterans, like you said, and others should definitely get a card. Balloon zombie too, I don't remember off top of my head...did you make a balloon zombie? I remember I mentioned about some of the og pvz zombies should be event cards, and I said balloon to be able to get over spikeweeds unharmed and whatnot, but I recall a pic like yours. Maybe I imagined? Ill have to look back. But lots of the zombies, and even plants(although they are covered pretty okay)
I like your boss broccoli too, and I am sure so will plenty of plant heroes lol.
And then back to raritys again... Why a superrare for the lure? Or did I read it wrong?
Edit: that lure vine reminds me of a plant that I was thinking...reason why it reminded me is its basically same, except it turns a random zombie into a 1/1 no ability zombie. Like a "not quite yet great zucchini"
