I seriously love Cattail. She's note only cute, but you just need one to kill lots of zombies. I also like Repeater, it gaves firepower enough to build defenses, but has an upgrade that can destroy a Buckethead Zombie in 12 and a half shots. Seriously, it's awosome. Garlic. I love this dude. It can explore the defenses of plants that can shot over them, as Gloom-Shroom and Starfruit. And also help to get a great part of the Split Pea, without having a Digger Zombie on the way. But it's awful against Gargantuars and Zombonies. Well, that's all, dudes!
