Basic pure Mekks. Make columns, dump Chalice into GY with Girsu or Morning Star, make Lib, grind out the game, negate with Secrets and Indigo, use Purple to cycle through deck. Sangan can provide emergency searching for Santa Claws or Orange, letting you deal with problematic cards such as Dragoon more easily (since your opponent probably won't wanna waste a negate on a simple search). Extra Deck is ordered in the best Prosperity banish order (in my own opinion), though keeping Link Spider/Dingirsu/Zeus around may be better depending on the hand you have.
