Here's the thing though: The more and more that I think about paralysis, the more that I think that it doesn't really matter anymore. The reason that I believe so, is that there are mostly slow pokemon like t-tar, jellicent, your standard OU Pokemon and whatever are slow this generation(with the exception of Lucario, the genies and I think the musketeers and some others I think), so thats why I'm questioning the actual reliability of thunderwave. You'd really have to rely on luck more often than not for it to actually paralyze your opponent so you would get a free turn to do whatever, pretty much.
In this ladder, I would find burn or even sleep to be more highly effective. Things like Conkeldurr? Put him to sleep, it's better than giving him anything else with what, a 1.5x boots with guts(at least, I believe it's that)?
What I'm basically trying to say is that, this ladder is just asking for nothing but status and stall matches, possibly. Offensive could be used to a good extent, but a lot of offensive teams rely on 120 BP moves, and having a Draco Meteor on every single pokemon in your team is going to get old eventually, and most likely predictable. You would have to hit and run everytime, or just run a Pokemon @ White herb for an effective sweep or something.
