I don't think this belongs in this section. The idea for threads here is to post decks you want people to help you with. Where would you like me to move it?
I believe there were issues the last time that lukce posted a Deck Collection because it was hard figuring out where to post it. In the end I seem to remember SG moving it to the Deck Help section, but since my memory is known to be...off...that might be incorrect. However, where else could it be moved?
General Discussion- I could see this in a sense, but then again I'm not sure. The TTW Study is currently in the General Discussion section, but then again that thread is more or less discussing patterns and trends for optimizing the most speed from the fastest decks, not about the decks themselves. Since there really isn't any discussion about how to build the best harm here...I'm not too sure about this location.
Rainbow Decks- Eh, I could see this, but not all of the decks are Rainbows so I don't think it fits.
Deck Help- There's two ways I interpret this:
1) The purpose of the Deck Help section is to increase feedback on deck builds for greater winrate, speed, etc.
2) The purpose of the Deck Help section is to help other players build a deck which fits their liking.
In the case of number 2, this thread fits here. jmdt also currently has his deck compilation listed under Deck Help, so I'm inclined to follow that notion as to where these types of threads should be placed. Of course, I don't exactly know how this is going to help other players since it will not receive use from more than 50 people at a time...but it's possible all the same.
