To the people saying that posting decks will make counter decks appear everywhere, you forget that in any game there's actually a minority that reads the forums and even a large portion of those that do don't care enough to change anything.
So I think posting decks is mostly harmless.
Posting decks is not harmless.
Are you forgetting about BL? The lack of restriction makes it similar to Silver League, and everyone in BL has a forum account. And in BL, they can use your own deck against you.
Anyways, from my experience, a properly balanced unupped firestall will do well. I've also had success with a mono entropy. But I won't post these codes, of course.
