Blitz teams are weak to Earth and Wind mains in general and Kimimaro with immortal Water team or Lightning root team, or if you are faster run control ninja like Ao on move 1 and just stop light armor.

Having played one on and off for about half a year now, they are more like rock paper scissor team you either win easy or loose easy, it can feel unfair if you meet one when your team is set up badly for it but over all they aren't that op, more and more Lightnings going root of warrior teams now.
