To start with - you need to understand the fundamentals of a CB team, namely, speed tuning. You are also missing key components for your team - you either need to build around unkillable/block damage, or you need to have a team that can survive a long time, which generally requires some combination of ally protect, DEF up, and strengthen.
I see that you have Seeker, so you should strongly consider one of the former teams, assuming you have the other pieces. You didn't post your full roster, so look through your champs and see if you have any of the other pieces - these usually include Maneater, Demytha, Helicath, Roshcard the Tower, and Emic.
you should run the budget maneater comp suggested by mooredrat when last you asked this question a week ago.
