I like Brainstorm at rank 30 because its fun. You may end up with any of the cards in the game. I run it with one Trickster, one Valk, and no Dreadbeards (I don't have any). To compensate, I include a LOT more bonus attacks (2 kinds of science zombies give bonus attacks, although one does cost 5 and is a more iffy add), the science zombie buffer guy, & the zombie that gives free tricks. Its all very synergistic -- science zombies become more of a big deal if you help them grow via bonus attacks and removal. Heck, I have two newspaper zombies, and they can win games. Put them down against the two small mushrooms, they kill one, and there attack goes to 9. 9 -- by the end of turn 2. If you have bonus attacks or removal in hand, that is a major threat on turn 3.
Apparently, there is a virtually unbeatable build with 4 Tricksters & 4 Dreadbeards, I'm FTP so I don't know, but I like playing it my way more anyway. Heck, I've won a couple times getting the dancing zombie on turn 1 from Brainstorm's power. With so many bonus attacks & so much removal, you can keep stuff alive if they don't have hard removal.
Paparrazzi zombie is not worth it imho. Better to bring no one mana zombies or at most 1-2 of the guys that go on the roof. Use Brainstorm's power (whichever one you get) instead.
