Unfortunately Hawkstar, peaks are more of a reflection of the state of the ladder in this case. Moreover, and perhaps equally unfortunately, not even the mighty TUbers can stand up to repeated dice rolls. If you insist on identifying yourself I have now rated your team and you can now see how it shows how a lot of what I have said here applies, redundancy, lack of synergy, etc. leading to innumerable weaknesses.
Froslass + Groudon is a unique form of offense that is entirely dependent on match up, it has a nice advantage against most forms of rain balance, but has trouble dealing with Tyranitar, Darkrai, and Giratina-O. Potentially very effective, but not reliable. (I should know I invented it...)
Trickroom's team is pretty good and I will consider adding it to the OP after browsing the RMT forum some more.
Syrim said this article focuses too heavily on rain, redundancy, and in the cores section should provide more practical thought rather than examples; I will make changes in the future, after flaying him.
The purpose of this thread is not only to educate, but to spark some discussion and see how others approach teambuilding.
