If you are looking to get the "insane" title, here's what you need.
You need to first quest with Darkmoon till you're friendly, once you get friendly with them it takes 18 decks to hit exalted which is a requirement for the Insane title. It may seem like a lot of gold (which it is) but remember that you can sell the trinkets back for a large refund of what you paid for the deck!
I sell the decks by themselves or as a package (save gold by buying in bulk)
My price is based around the time of month it is. The closer to Darkmoon the more they cost.
